Glockenspiel plays the music encoded on credit cards

This is the Brockenspiel, a project by Brock Craft. It reads the magnetic strip on credit cards and swipe access cards, zips them through an Arduino board and triggers solenoids which bash the chimes. There's no real logic to the music - numbers 1-8 trigger chimes, 0 and 9 are rests. He's had it installed at work for 6 months, although it doesn't seem to be connected to an actual security system. That's a shame, because it would be nice to announce everyone's arrival in the office with their own personal chime. Brock will be demonstrating it at Dorkbot London in a couple of weeks.
