Artistic apps

Hi all,

I’m preparing a course on creative things to do with your smart phone or tablet. I’m looking for apps that create something artistic from your smart phone data.
So far I’ve discovered two: Figure running and Frickbits. They both use gps. I was wondering if any of you know about other apps? Maybe apps that make use of other smart phone data to automatically create something artistic?

Thanks very much in advance for any suggestions, best, Danielle.
