This is really cool!

A steampunk musician called Yoshi Akai has made a magical lego music-making machine. It’s called the “Sequencer MR II” and turns coloured lego blocks into sound:

“A contraption that uses three-dimensional Lego structures to emulate a three-channel, eight-step sequencer, where each differently colored plastic brick produces a different sound and complex combinations (including tremolo and overdrive) are possible when the blocks are stacked. Akai tells us it works using resistors embedded in each and every block, with parallel networks of resistors formed as the bricks pile up, equalling lower resistance and thus a higher frequency sound generated by the contraption. Akai says he’s building sound more than playing sound.” – engadget

I want a play..
