Algodoo

Inspired by [scene]46326[/scene], in this scene the blue circle tries to mantain a constant speed of 1 m/s and avoid obstacles (killer objects). everything is automatic, just press play. When the particle dies press CTRL-Z or open the console and type "scene.my.spawnautoma" you can also add a second particle (or a third, fourth ...) by typing the same command in the console.
Initial conditions are random, so if the particle is spawned on an obstacle press CTRL-Z.
Beware of memory consumption, i dont know if there is a bug, but in a long simulation Algodoo took all my ram and the pc hanged.

<edit> Uses lasers! Algodoo Only <\edit>
