The Uzu app for iPad uses up to 10 fingers. It is a particle visualizer, only notable to me because it was reviewed by Ars Technica. The video linked from the review gave me the sense that it was a labor-of-love for the creator and probably fun to use for 10 minutes, but not enough to cause me to purchase it. On further thought, if the Xavier Institute had an app for training its mutants that possess hand-borne energy powers, this would be it.
