Build a programmable mechanical music box

Some time ago, I posted about the Gloggomobil, a programmable music machine. Here is an Instructable for making a very similar device. On the Gloggomobil the movable pins trip hammers which strike the keys on a Glockenspiel to play the tune. This device is similar in construction in most respects but the tune is played on a large version of the thumb piano.

Here is a link to the Instructable on how to Build a Programmable Mechanical Music Box.
