That is cool. I love the touch of the little dust explosions off the paddles. For anyone else that wants to start playing with canvas, let me relate a gotcha that drove me absolutely nuts. And if I'm mistaken on this, someone please set me straight.<p>The issue: You can <i>not</i> paint pixels directly onto a canvas. Instead you create a buffer of specified dimensions, indicate what colors to make its pixels, then overlay that buffer onto the canvas at a specified location. So it is possible to wrap that functionality up into an api that lets you simulate direct pixel painting, but it is not possible with raw javascript. Lines and other shapes, on the other hand, can be rasterized directly onto the canvas.
