I was recently introduced to FlipMu via the thoughtfully random EYEBEAM reBlog postings of Jon Cohrs.
"FlipMu is home to the collective works of Owen Vallis and Jordan Hochenbaum. Interested in exploring the artistic and aesthetic implications of fusing interactive design, sound, and technology, FlipMu has created works ranging from large scale interactive multi-touch commercial installations to live musical performance using custom hardware and software."
Check below for samples of their work...
