This homebrewed Wii App called Wii Physics is similar to Microsoft’s Physics Illustrator and will let you test out your ideas before applying them in real life.
Wii Physics is a clever little homebrew app. You use the Wiimote to rotate, size and place objects on a stage. Pulleys, ropes, gears and joints can be used to connect objects together, and when you press the play button, a 2D physics system is turned on, causing the objects to fall and interact with each other.
