Bounce 2 is a physics based musical app with colorful shapes and playful multitouch gestures. It's great for kids as well as adults who enjoy interacting with a  real time 2D physics simulation while also creating pleasant melodies. The very intuitive controls allow for even very young children to enjoy Bounce.

The kick starter project is raising money to help fund further development of the musical features of the app. For more information go to the kickstarter page: http://www.kickstarter.com/projects/941797232/bounce-2-notes
