FOSS gamedev and creative worlds

I'm thinking of seeing how far I can get through http://nand2tetris.org/ using Mesecons with the Manchester (UK) CoderDojo. If anyone wants to help out or has ideas/experience with the Mesecons logic gates please drop me a line.

This is an awesome idea, I'd love to see this. I don't have much experience, though :P
