This is an application for the iPad. It's a gravity swarm simulation, you create gravitational forces with your fingers and watch how the swarm interacts. Shown here is me using it in the simulator (if you hold ALT you can get 2 touches on the screen but they are mirrored) but it supports up to 10 touches,. Developed with http://www.libcinder.org It should be in the app store within a week or so, ill update this post when its available.
