This is neat:

David Youd picked up a “DIY Music Box” from ThinkGeek, and decided to port some Ultima 3 game music to it…specifically, the theme.

This presented a bit of a challenge, of course, since the music box has a two-octave diatonic range. That is to say: it only plays natural notes (e.g. the white keys on a piano). Despite this limitation, though, it would seem that the attempted turned out rather well!
