Japanese artist / designer Yoshi Akai has quite the repertoire of zany instruments and synthesizers. Not only do they have a wicked steampunk aesthetic, but the control formats range from credit cards to wireless signals. Cool stuff all around. This particular one is a 3 channel, 8 step synth that uses different colored LEGO blocks as triggers. You can even create 3D shapes to get really crazy.
