I wrote this little sketch on Sketchpatch today. It looks good on a fast machine: at work, I have 2.66 Ghz iMac, and it runs great there, but my 1 Ghz powerbook at home is choking on it.
This is the same idea as this old straight java applet. I wrote this a long time ago for the 5K competition for the coolest java program in under 5K. Might have been related to these folks, but it was a long time ago.
The Java version runs better. I'm not sure how Sketchpatch works exactly, but it definitely is slower than straight Processing applets. Maybe that could be improved?
In other news, I like this flash version of the old moon lander game.
