Just saw this linked on IRC.
Crayon Physics Deluxe looks like a really fun game, makes me wish I had a tabletpc to play it on but I think I’ll see how well it works with an attached graphics tablet. The game was a year old on Jan 7th so Petri is celebrating by allowing people to pay whatever they want for the full game until Jan 15th. Fantastic idea, I hope he does well from his sale. I found out there’s an iPhone App version too, awesome.
Tobias Weyand did a great ds homebrew physics game inspired by the original Crayon Physics called Pocket Physics. Tobias describes it as is a mashup of The Incredible Machine, Crayon Physics and Line Rider, Craig Harris from IGN describes it as “digital crack” 🙂
