The Crayon Physics Deluxe must be one of the coolest touchscreen games ever. The aim is very simple: take a ball to where the start is. The tools to do it are a crayon and your imagination, since whatever you draw will automatically get recognized by the physics engine and put into motion over a piece of paper. Microsoft must buy this game and ship it with every Tablet PC. And somebody should port this to the iPhone. Pronto. [Kloonigames]
