First of all, I know this is a terrible video. I only have myself and my mobile phone to blame. But I wanted to post this anyway. It’s from OpenNight #4, a night of FLOSS inspired electronic music and video from the people of OpenLab, which was held yesterday at the Fleapit in Hackney. The music you hear is the combination of a computer mouse being used to control frequency horizontally and amplitude vertically, and thus simulate a theremin, while an audience member plays pong (poorly) against the computer, with the hits and misses triggering different (and evolving) sounds. Dour music, but I like the idea.
