This is a system that has the cats to communicate with the ground to find the angle they are standing on. You can drag the cats around. If you change the settings, hit the green flag again. This is an example project to show a possible way to communicate between clones. When a clone is dragged onto the ground, it will ping the ground to give it the average angle its standing on.

This is impractical for standard projects, because it uses colors to transmit information. It also randomly doesn't work on certain OS's. If anybody knows a better method, please do share.
