Just for the fun of it. The project starts by animating a circular image I drew. To draw your own, click Edit. Remixing will save your image. In Edit mode, if you click the image, you will draw with the color shown in the Swatch in the lower left corner. To erase (draw with transparent color), hold Space and click the image. To change color, click the Swatch. Then adjust the RGB sliders, or click the image while the sliders are showing to select that color. To hide the sliders, and continue drawing, click the Swatch again. All code by me (@kriblo).
