RoombaMidi is a Mac OS X application that turns the iRobot Roomba vacuum cleaner into a musical instrument – complete with flashing lights and spinning.
Before you ask why, watch the video… then ask why…
It’s a lot of fun, though, and allows the vacuum cleaner to be controlled from top-end apps like Ableton Live and Logic.
Plus – get this – you can control up to 16 of the little chaps, one per MIDI channel. Jazzy… your own orchestra.
