Found a game that might appeal to some of you guys. It's called Crayon Physics and it's a puzzle game where you have to move a ball from one part of the screen to a star on another part; you do this by drawing shapes that then become objects on the screen. You can make platforms, weights, ramps/wedges, ropes, gears/notched bars/ratchets, etc., and you can delete them if they get in the way later.

Here's a sample video. Wall-E fans may like this person's solution
