Robot Takeover was a fund raising event for BuildBrighton which took place at Komedia on 30th October. BuildBrighton designed and made a digital pseudo-theremin (the transparent orange box in the photo) for the electronica DJs Evil Nine who performed after the event. It is a MIDI controller that works by sensing arm movements using ultrasonic range finders.
