I’ve seen some stuff
Blinkynoise boxes Right , so I was at the Bent Festival a few weeks ago, which turned out to be more of the Chiptune festival, since most of the stuff I saw was made from scratch. These little suckers you could actually buy. They make a nice coffee table item, or you can rock out with them.

While these were cute some stuff looked a bit dangerous. This was a biofeedback setup where the performer was literally electrocuting himself while he played an exposed circuitboard. Yikes!
