In 2007, steampunk musician Yoshi Akai wrote his master's thesis on how to turn color into sound, and he's been dreaming up unorthodox ways of producing music ever since. Case in point: the Lego Sequencer MR II, 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 f
