Bubble Harp draws bubbles around your mouse’s strokes, recording and replaying your movements while creating music. It’s a combination of drawing, animation, music, art, geometry, and gaming. You can record long movements of a single point, or stream many points out of your cursor like ink. Through the pop-up control panel at the screen’s bottom, you can change from single points to streams of points, change graphic and sonic parameters, and load and save files. 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 a Mac application that also makes music.
