Ohh, for those with limited internet speed for viewing the video, this is the explanation of the game taken from the original website:

Crayon Physics Deluxe is a 2D physics puzzle game, in which you get to experience what it would be like if your drawings would be magically transformed into real physical objects. Solve puzzles with your artistic vision and creative use of physics.

But should I get the pen? Humm, I guess I could use my mouse..
