Here's an idea: Pair it with something like brain.fm and market it as a relaxation/meditation technique.

Also +1 for the gallery idea, and not worrying about animations, just a gallery with voting and show off the ones that get the most votes.

Like: http://www.colourlovers.com/palettes

Another idea from that: take the palettes from colourlovers and add those as something people can choose from to do the drawings with.
