Who said that electronic music couldn't be silly? Certainly not the folks at Minimalogue. The South Korean graphics firm recently built Knuckle Visualizer, a synthesizer that replaces buttons, knobs and sliders with fun bits like jelly beans, rubber ducks and tiny matryoshka dolls. And yes, it works -- while you won't get a yarn-based waveform display like in the video below (that's just for show), the Visualizer itself beeps and squeaks like any "serious" synth. This art project is clearly a one-off, but there's a making-of clip that could help you recreate it in your own studio.
