About physicSketch
I inspired this demo by a movie about the Crayon Physics. As the movie shows, when you draw something on the above canvas, it starts moving under the Newtonian low.
This demo is using Mr.doob's improving version of Box2DJS. Thanks Mr.doob!
How to Use

| Draw Line | Drag your mouse on the canvas. If the starting and the ending points are far enough, the track becomes connected lines. |
