Explanation
Tower of Hanoi is a puzzle where you have some different sized discs stacked on top of each other. Rules:
- there are 3 pegs
- the discs are all stacked on one peg in the beginning
- objective: move all the discs to another peg
- move one disc at a time
- you can't put a bigger disc on top of a smaller disc
The contraption to the right of the marble dispatcher generates the solution. We have the binary counter on the right, and the memory cells on the left. The vertical level corresponds to the disc (top level is the top disc), and the colors correspond to the pegs (red: left, green: middle, blue: right). The state (color) of a memory cell corresponds to what peg a disc is on, e.g. if the top cell is green, the top disc is on the green peg.
When the binary counter flips a bit from off to on, that triggers the adjacent memory cell to rotate and change state, representing what peg the disc should move next, e.g. the top cell changing from red to green means the top disc will move from the red peg to the green peg. The rotation of the cell triggers the corresponding marbles to dispatch.
The contraption keeps track of where the discs are. The solution to this puzzle is an elaborate way of counting in binary. I've watched this thing go so many times I have an intuition of why it works, but atm I'm not sure how to put into words. This section on the gray-code solution is what I'm implementing, though it's hard to understand
Disclaimer: This contraption is basically a really fancy counter, so I'm not sure if it's appropriate to call it a computer. With that said, I think it gets the point across much more clearly than, say, "solved by a mechanical contraption/counter/algorithm/thing"

I don't think Photoshop would much use for something like this.
Instead something like Algodoo would be better suited. I played around with it years ago and it's pretty good but I don't have the time to try an recreate this problem at the moment.
I remember when that program was still called Phun. I haven't even thought about it in years, but it was fun as hell for a sandbox physics simulator. I probably still have a license for it somewhere.
Link. http://www.algodoo.com/
It's called Algodoo, and it's free: http://www.algodoo.com/
I once used it to model several different types of volcanoes for a high school project, it worked pretty well. You can also attach graphs that measure velocity and acceleration over time.
Try phun.
It's a physics sandbox that is really fun. It will get him started developing an intuition for mechanics long before he's developmentally able to learn them in an academic sense.
Weirdly enough; Algodoo. It's a physics simulator, but I'm so familiar with the shape manipulation it works for making sprites and planning things like this, moving furniture around etc. Here's a video demonstrating the potential as a graphic editor.
It used to cost some odd amount but it's free now. I can give you guys a dropbox link if you want the drop in parts I've made for Factorio.
We had these in my college. They're really useful for some stuff, such a sketching since you can pretty much use Photoshop tools for making circles and stuff. My teacher was even playing around with Phun in there one time. But when it comes to actual writing, it doesn't feel anywhere as good as a real board. Then again, the main program has handwriting recognition that automatically converts your writing to real text, which is cool.
Manufactured and software imaging when that driver was current. Most companies do not update their stock image. Dont know what SystermRequirementsLab is, or driver booster. Sounds like 3rd party programs that probably install bloat, and send your system data to whoever. You need to read about updating your driver manually, from reputable sites, such as the graphics card manufacturer or Acer directly. Id imagine your laptop comes with some sort of software from Acer already that will do this. Otherwise, http://www.algodoo.com/update-drivers/ start googling, and learning how to do it without installing needless bloatware to your computer.
Thanks to /u/_Joexer for reminding me about this program in his post.
I'd also be happy to take a request or two if anyone is interested in seeing different angles/armor shapes in effect.
(Note: the simulation is extremely simplified, pretty sure that's not exactly how shells behave irl, or even ingame).
This image is from a physics game called Phun. The game evolved into more of a learning game called Algodoo. Its a ton of fun if you like physics sandbox games. I believe you can even play it on smart phones now. http://www.algodoo.com/
Not really a game, but Algodoo is a fun 2d physics sandbox program. You can create your own physics-based contraptions, like vehicles and all sorts of things.
And, I guess you could call Minecraft an educational game.
Aside from rendering only chunks, the game is also based on a "falling sand" mechanic concept. Only difference is some entities have actual physics.
For air pressure / wind etc. you'd need to simulate physics for each pixel. That would be extremely heavy on resources and the game is already CPU heavy as it is.
EDIT: they could also do something similar to Algodoo - simulating groups of particles. That's still super difficult and possibly not in game spirit, though.
You could try Algodoo
Disable air resistance and gravity, create some shapes and attatch tracers
The best way is probably to learn programming. That gives you virtually limitless freedom
I made in a program called Algodoo Physics. I got it off the Mac App Store for something around 30 bucks, but there's a free version that's only lacking a few features available here. EDIT: Apparently there's also a sale on Algodoo Physics today. I would recommend grabbing it for $5 opposed to 30 bucks.
years ago it used to be free and was called Phun. It's basically an extensive physics sandbox where you can build anything from a plank with wheels to a fully-automatic rifle. Look up some of the insane stuff people have made.
Care to share that algodoo model you made?
/edit, I ended up making my own model. It's not so pretty and I couldn't be bothered making my own faucet so I borrowed one that was already made and in the model library.
Anyway the borrowed faucet is fast pouring and #1 does indeed win.
Last non request Solid AP shot https://gfycat.com/FakeBabyishAtlanticsharpnosepuffer It incorporates all my efforts and is available on Algobox here: http://www.algodoo.com/algobox/details.php?id=136214
It's a super powerful and free physics sandbox. There are downloadable creations and lessons (designed for in-school use by teachers, but anyone can check them out) and places to share your own works.
One of my favorite things to dick around with, but it does have real applications too.
Algodoo
It comes across as a kids game (maybe it is), but I've killed a lot of time in it's 2.5d environment making creations work. The physics of it try to be as customizable and precise as possible.
You can have a software version if you want guys for now.. go and download Algodoo for free, and download my Ball Control Modules Scene Infact I just recommend the program in general for people in this sub.
I've uploaded 14 scenes to the algobox and added links to the videos and download links for the scenes. I also added links on all of em' for this subreddit to hopefully spark some traffic.
Its just fuel efficiency like any automobile. The fuel is food and the engine is muscles and a machine.
These machines/vehicles would be awesome if there were zero crafting recipes, and instead just freeform building like algodoo
http://www.algodoo.com/wiki/Home - I've been using this program since it was in beta, so I got it pretty cheap, but it looks like now the edition that I got for 9 euro costs 45... Regardless, it's on sale right now for 22.5 euro, and is a really really good program.
Among other things I've learned a super limited and obscure programming language with very little documentation and very few users (Algodoo Thyme) and with that, about a year ago I made a computer using Thyme that natively ran SuBLEq.
you have have to make an object spawn another object with all of the same attributes. if you copy the object and paste it into a script box it gives a whole lot of stuff, but if you take all of the object related stuff and put it into a spawn polygon script, it will basically spawn that object. you have to delete a few lines too with the entity and geometry ids. you can see how to do it here: http://www.algodoo.com/algobox/details.php?id=248066
So from what I understand is the target moves at a constant rate but I assume your missile does not. I think what you need is to calculate how long it will take the missile to reach its target. In your example if the target moves at 25m/s then if your missile is 1 second away it needs to point 25 meters ahead of the target at that time. But if the missile is .5 seconds away it needs to point 12.5 meters ahead of the target. I've done something similar in the past (http://www.algodoo.com/algobox/details.php?id=90327) but I used constant velocities to make the math easier.
If your missile has a top speed it will be easier to calculate. So instead of always trying to calculate angle maybe wait for the missile to reach top speed, find the distance between the missile and target, find time to reach to target, and calculate the targets position after that time has passed. And that is the angle you want.
I hope this helps.

Not sure about the lag. How powerful is your computer?
You can go up and down in the console with the PgUp and PgDn buttons on your keyboard, but it only goes so far.
One really helpful thing for learning thyme is the search function. In the console if you type "/" and press enter it will list all Algodoo functions. Or you can search for any keywords, /app. or /entity or /key etc. For finding created variables if they are global, scene.my.whatever, use the search /scene.my. . And it will list them.
You can also check out the Algodoo forums. http://www.algodoo.com/forum/viewtopic.php?f=13&t=83&sid=8dba793be0e368977dfd7748aff340f8
idk this will help or not, but there some my old scene and here is used some simple collide counter (left part of scene): http://www.algodoo.com/algobox/details.php?id=140314
Rotor is sending data to scene.my variable that then used in rectangle text area.
PS: text field must be of type "string" so there why added "" to variable. U may mix text and variables in your own way("\n" for break line, "\t" for tabulation, "\\" for \), like:
"Number of collisions is "+scene.my.coll_counter+"\nFor set number "+scene.my.set_num
PPS: This is a simple way, there more ways to do it, but it depends on required task etc. Like instead in-field scripts use event-related fields(like "postStep" or "update").
You can use a function called "set.insert(array, element)", or "math.addList(list, list) if you're adding lists.
As for a library, you can check this list: http://www.algodoo.com/forum/viewtopic.php?f=13&t=83&sid=88edffeb9175791e9cae501644016ede
Read angle from some control rotating object and write it with scripts into bendTarget field of hinge (without motor if you want uniform rotating speed). Set bend=true and bendConstant alike very high (1e+5 or more).
You also might use hinge rotation transmitter with active brakes and bend (as a measure if braking not enough), alike as a mix of upper things there: http://www.algodoo.com/algobox/details/135916
If you want simple gear design software, try Woodgears's Gear Template Generator.
If you want to play around with more complicated mechanisms, with springs and things, and 2D would be acceptable, perhaps Algodoo would suit. (Not really CAD, but much easier to get something "working".)
Hi LewisgMorris, I would like to try it myself as it sounds fun, do you have a link to the repo?
Also, the video link is not working for me.
Is this similar to Algodol by the way?
To update drivers
http://www.algodoo.com/update-drivers/
If that doesnt work and you have just a regular rotmg account and not a steam account you can use flash projector to play. A tutorial for it here

This almost looks like Algodoo actually, but might be something else.
Actually on second thought I don't think it is unless it's a different visual render (possible for saving CPU). Algodoo doesn't usually do too hot with this kind of particle count, still fun to play with though.
> Is there any software where I can create anything, like custom technology/transportation,
Wow that is vague. Like really vague.
> then test it to see if it works with real life physics.
For simple 2D contraptions something like Algodoo works nicely.
Very cool. Now I don't know how helpful this is, but there is a 2D physics sandbox program called Algodoo, its free and you might be able to make it more realistic in there though. Not 100% sure though.
If anyone wants to know what game this was in it's called Algodoo, it's one of my favourite games and it's free! (Although the sounds were done outside of the game, it has no sound)
As someone has now identified the simulator as Algodoo, you should read their FAQ:
> Are simulations in Algodoo accurate and correct, or is this just a toy?
> Algodoo is indeed a digital toy, and nevertheless simulations are of very high quality, using cutting edge scientific methods for multiphysics simulation. However, there are some things to keep in mind:
> The time step in Algodoo is by default 1/60 second (60 Hz), so any modeling of real-world physics happening at shorter time scales will be hard to reproduce.
That alone is more than enough to produce non-physical results such as those displayed on the page, because even real-worlds physics that seems to be happening on longer time scales will lose accuracy pretty easily when the resolution is only 60Hz.
Very nice website!
>Entropy seems tricky to define. Does my explanation work?
For the rotor to turn spontaneously, entropy has to increase in this isolated system, so the demonstration is correct. However, I would use it instead to demonstrate how pressure and temperature work (e.g., you could add sliders to introduce inelastic collisions that will simulate cooling). To demonstrate entropy specifically I would use a mixing process. Start with blue particles on one side and red particles on the other side. Open the barrier, and plot the concentration of each colour in each of the compartments over time.
P.S. I don't know how easy it is to use the js physics engine. If it's laborious, you might want to take a look at http://www.algodoo.com It's very easy to prototype demos in that simulator.
As of now, mostly a shitty Asteroids clone for a CG assignment which never got really finished.
Other earlier projects included Translating Neuronball, Algodoo and Celestial Command into portuguese, then completely forgetting to mantain the translations up to date in all three of them.

It's a shame but I did come across a drag scene this guy got his dragster upto 400m/s + on 100hz. I lowered the hz to 60 and it still worked ..so wtf?
Edit: this one http://www.algodoo.com/algobox/details.php?id=30140 he made it in Phun but works in latest version of Algodoo
Fine. I'm not doing anything important, I've got some time to spare. I've built you a simulation in algodoo, a 2D physics engine. Laid it out nice and simple, the purplepink walls are frictionless and serve only to keep everything in line and the springs straight, the block on the right weighs 6kg, the blocks on the left weigh 3kg each for a total of 6kg. pull down on the launchpad, let go, and observe as the side without a shock absorber providing a damping effect goes higher than the side that absorbed some of the impact with a damping effect.
Here's the video: https://www.youtube.com/watch?v=mpMMjqj2sLw
Algodoo is free and you can get it here: http://www.algodoo.com/download/
Here's a copy of the level: https://mega.nz/#!t9R3ETCI!dc6xxPJfS04SBpyu7h4bnTmfynUZqLCS1jnu1sZjGuQ
My guess is it would be the equivalent of the vehicle going up a ramp with higher inclination; plus some additional effects due to the sudden change in the speed of the "ground" relative to the wheels.
I don't think I got enough knowledge to be any more precise than that.
edit: equivalent only in terms of the added vertical momentum; the vehicle would not be angled up the same as if it was a static steeper ramp; but there might be some effects on the vehicle orientation due to the tires and suspension bouncing as if they were hitting a steeper ramp, I'm not sure...
edit2: You could probably get a reasonable approximation by creating those conditions in Algodoo (free). Don't forget to make the wheels be powered, and to have a reasonable suspension.
when I saw the plans you made mimicking the movement of the boxes, I first thought of this:
Thank you for giving me a damn good idea on how to approach movement-oriented projects like this! As a matter of fact, a friend of mine has been meaning to make a box just like this for his wife! She has a sewing box already, but needs a bigger one.
Algodoo, its free and you draw in 2d and interact with whatever you draw with a very nice physics engine, http://www.algodoo.com/download/
see here to see some creations: http://www.algodoo.com/algobox
Can't believe nobody's mentioned Algodoo yet. (Formerly known as Phun, it's a funducational 2-D physics sandbox which is like this but better in every way because it has LAZORS!!!1!)
may not be insane, but some fun free physics sandboxes include Algodoo (formally phun), and The Powder Toy. You could also check out Rigs of Rods. About all I could think of at the moment for free physics-focused games
It's not a game, but try Phun. http://www.algodoo.com/download/
This is the older version, with which I am more familiar: http://phun.en.softonic.com/
You can create scenarios, liquify objects, and demonstrate what happens. You can set densities, I think.
Some parts may look ugly but are functional. This machine turns odd shaped rocks into almost perfectly round circles and uses them to move some sort of cars. It took me a long time and help from a friend to get this running so smoothly.
You could in theory place my Octacut 3000 behind the production line instead of the robotic arm thingy but the lag would overload every computer.
Algodoo. It is not really a game, but a physics simulator but some of the "maps" made by other "players" are really fun. Also you can try various psysics based experiments.
