I constructed an interactive geodesic dome consisting of 120 triangles with an LED and sensor at each triangle. The dome is programmed with an Arduino to light up and produce a MIDI signal depending on which triangle you place your hand. I designed the dome to be a fun display that gets people interested in light, electronics, and sound. My friends in the video are: Ena Selimovic, Alex Papiu, Cody Greer, Jim Pearson, and Yuval Bonah. This video shows the dome playing the following games:
