Phun with Physics

Computer Science Emil Ernerfeldt came up with Phun for his Master of Science Thesis. The game/tool can be used as a educational program for learning about physics concepts like restitution and friction, or it can be used just for fun. After downloading Phun (works on 32-bit and 64-bit systems), you can navigate around the scene and begin drawing shapes like straight lines, circles, boxes, planes, springs, chains, hinges, and other polygons. You can even add features like water, fix joints, rotational joints, hinge motors, and more. Of course the "phun" is in the way all the elements can interact with each other. If you're still confused, check out this video of Phun in action. Doesn't that look like...Phun? (Not enough phun? Also see the Physics Illustrator for Tablet PC.)
