LEGO sequencer builds sound from colored blocks
Behold the awesome majesty of the Lego Sequencer MR II. This brilliant instrument is the work of Yoshi Akai, an avant garde artist/musician/audio mad scientist from Japan currently blowing the minds of folks the world over from his base in Sweden. Akai has turned a background in textile art and design and an interest in sound into some of the most unusual musical instruments ever.
In this particular design, the colors of the blocks determine the sound being played. Stacking multiple blocks into a three-dimensional design creates weird, complex sounds. As he says of the instrument, "This is building sound more than playing sound." Yes, it is. And it's also building awesome.
