I have ben doing much research into midi controllers of late and looking into options such as iPad with touch osc, apc40, novation.... building my own ect.... came accross this little gem today where you convert a $50 bliptronic synth from thinkgeek into a monome clone for $60 (usd). 64 buttons and 4 trimpots, seems like ideal cheap resolume 3 controller.
