I read it because of this game and I highly recommend you do the same. It was definitely Davey's inspiration, or at least a big part of it.
Yes, wanted to have something to always remind me of the game and its philosophy. Couldn't find anything online so decided to make one myself using:

and just a regular wooden cube
Paint wise it's just Primer+ 3 colours, Glow-in-the-dark Green and Black + Grey (mix for the darker grey)
P.S. I'm a designer thus the word Design. For anyone trying it out, do a word that inspires/describes you!
