About a week ago I attended a friends birthday party and came across an interesting toy.
So here is this 1-bit groovebox, one of many designed and floating around by Shifty with the M.I.T. media labs. This thing makes incredible glitched out, mayhem sounds. Bleeped out insanity, corruption and chaos in audio form. An MP3 for your listening pleasure.
With that said, if interested enough, build your own. The schematics and all other needed information is located through the website.
