I recently came across this game called crayon physics. It’s a physics puzzle game in which you have to draw objects in order to solve its puzzles.

The art style in the game has been designed to look like you are drawing on paper and when you draw it looks like you are drawing with a crayon. When played with a tablet or used on a tablet pc it is really effective at giving the impression that you are drawing on to paper.
