This little design created a lot of interest at Dev8D software development conference this year. E-beam gestural drawing software was used as a visual addition to a bespoke laser harp that acts as a MIDI device. The E-beam whiteboard software translates the movements of the pen to an onscreen canvas while interrupting the path of a number of laser beams which in turn controls a synthesiser in Abelton Live. The system makes use of the Arduino environment, bespoke electronics and hacked MIDI data cables.
