If you've got a collection of old Famicom (NES) consoles lying around, we can think of worse things to do with them than wire them together in a flight case, link them to a Roland 606 drum machine, and turn them into a mega percussion studio. We have no idea what this sounds like (and the link to the creator's blog is dead, no doubt because everyone else is wondering the same thing), but one look is enough to convince us that, no matter what, it rocks.
