In order to make the simulated area larger, you must make a save and put it somewhere that you can find it. Right-click on the save and open it with a text editor. Scroll to the bottom and there will be a list of settings that you can change. One of those settings is called "scale". The default number as you can see is 8, if you change it to 4 you will have twice as large of a map, if you change it to 16 you will have half the sized map.
As for screen capture - any screen recording program will work. FRAPS used to have a setting that would only record at the framerate the game is running at, however that feature may not still be there. I use iMovie to do my work, if you find a similar program for Windows you would need to break the video into two pieces - the first part is normal speed as the bomb is falling, then when it blows up you would need to change the speed of that section until it looks realistic.
Sometimes, for example on the Cannon videos, the whole thing runs at a constant, slow speed. I use FFMPEG to speed the video up by 5x - it's a great free program. Check it out:

Excellent question! Here is a permanent solution:
Download the 64-bit version of this program, RunAsDate. It allows you to make OE-Cake think it's a different day without actually changing the date on your computer.
When you download and run this program, select OE-Cake in the first box asking for the program. Set the date to November 1st, 2007. OE-Cake actually expires on Nov 7th `07 I think so any time before that day will work. Write in the name 'oeCake' and create a desktop shortcut. When you click this shortcut, OE-Cake will work!
When you run OE-Cake, be sure to try out some of the files in the Sample Creations folder. There's a lot of interesting stuff in there.
OE-Cake is all CPU, and it's performance under a Virtual Machine was very remarkable, even though it didn't have the fire and water shader (could just be my VM setup tho). If you're going to do the VM route make sure you chose OSX that way you get the OE-Cake with the most features.
There's always a WINE port.
Since OE-Cake is very simple, the Darling project might be able to run it.
