Bubble Harp draws bubbles around your fingertips, recording and replaying your movements while creating music based on the animated forms. It's a combination of drawing, animation, music, art, geometry, and games.
Bubble Harp was first released as a work of interactive art by Scott Sona Snibbe that was only available in galleries and museums. Now it's available as an iPhone and iPad application that also creates generative music. Bubble Harp was built for the iPhone and iPad with the help of openFrameworks, and uses the Triangle library by Jonathan Shewchuk.
