Crayon Physics Deluxe lets you draw objects on the screen by clicking and dragging your mouse or by drawing with the stylus of a tablet PC as in this video. The objects you scrawl become part of the game world. The goal is to create objects that propel a crudely drawn ball toward a crudely drawn star. There is no single correct way to scoot that ball around the fun is in exploring the options. Within seconds of hitting start you''re furiously scribbling blocks and ramps and wedges and seesaws whatever it takes to reach the goal. Some players may get sidetracked creating hilariously inefficient Rube Goldberg devices. Others will forget the objectives altogether and just draw. (If you want to try it yourself you can download a simpler demo version of the game here.)
