This is brilliant. It reminds me of the old HP ScanJets, which came with SCSI commands to play musical notes[0] (someone at HP must have had too much free time on his hands ;)). Some videos of the scanners are at [1] and [2]. Another interesting hardware hack to produce music is the "hard drive speaker". You can see some of them in action in a rendition of Radiohead's "Big Ideas: don't get any" [3], as well as various printers and other devices used for their auditive side effects.
