Crayon Physics

This movie illustrates a strategy game that relies on interactive drawing and 2D physics to solve complex puzzle games. Developed by Petri Purho, its principle is well adapted to our multitouch table which offers both the tactile intuitivity and a collaborative puzzle solving platform, mixing real objects (the fingers) and virtual objects (the hand-drawn shapes) into an interactive game board.
