This video is made by Sascha aka handtapeloop who is an artist and music teacher in Berlin. Sascha has specialised in combining sounds with graphics via physical means, eg. using oscilloscopes or, in this case, plotters.
It's a great use of the AE Modular system to create a beautiful installation:
Sascha will be presenting his sound art projects at this year's Superbooth as well as running his very successful tape loop workshops again.
