Crayon Physics Combines Science and Puzzles

IamAHack writes "NPR covered a new game that seems like it would have great appeal to Slashdot readers: Crayon Physics. Quoting: 'A new computer game went on sale this week. It's not a blockbuster like Halo or World of Warcraft. There's no first-person shooting, no sports, no guitar, no microphone. Instead, there's a crayon. The game is Crayon Physics Deluxe. It's a simple, mesmerizing game created by a 25-year-old independent games designer from Finland named Petri Purho. "It's a game where your crayon drawings come to life,' Purho tells NPR's Melissa Block. 'You draw stuff and your drawings behave physically correctly. As soon as you release the last button, the laws of physics are applied to your drawing."' A demo is available, and Opposable Thumbs has a review of the game."
