Algodoo

A simple hovercraft that goes wherever the mouse is. It tries to make the blue laser's collision position the same as the mouse position. In my opinion, it works pretty well, but don't take my word for it, download it and try it out!

If you use this in one of your scenes, please make sure to give me credit somewhere.

P.S.: As I was typing this out, the box that says where the mouse pos is kept changing with the mouse, so the number it says in the picture is where it was when I was typing this out.
