John Cage assuredly approves of the Networked Piano

No, it's not an analog-piano interface for playing MIDI, so don't even bother dreaming about how amazing your AC/DC
MIDI files would sound on your Steinway; it's a network traffic analyzer that strikes a key when an attached computer has network activity (that's up to 88 computers). We imagine the novelty would be worn out within seconds, but just for laughs we'd leave bittorrent on all afternoon while we're out; we're sure the incessant C# note will eventually drive our bass-pumping neighbors absolutely up the wall.
