Canvas Painter As Alex Russell said, "this is the sh*t", and he's right! It's apparently built on Dojo and is basically a draw/paint interface with two brushes and some basic shapes to add to your canvas. You use sliders to manipulate the color of each element, and best of all you can record an animation of your work as you build. I haven't figured out how to save the animation yet, but even if you can't it's an amazing demonstration of what the Canvas tag will add to the web.
