The Roomba family was out caroling. They stopped by and sang a few songs. I caught a few on tape. I think they were a little tipsy on mulled 30W or something. This was a demo of RoombaMidi2, a Mac OS X program to turn your Roomba into a MIDI instrument.
Nothing says Happy Holidays quite like Roombas caroling, drunk or not.
