Jesse Lucas's Dyskograf reads graphical disks marked using felt tip pens; the mechanism translates the drawings into a musical sequence.

    Here’s what it sounds like: http://www.youtube.com/watch?v=gwvnS1mqX78

    it uses a 12″ (LP record) film disc, with 57 concentric tracks of optically-coded audio (very similar to 16mm movie film).

    The good part is that many of the pre-recorded disks sound delightful to modern ears, and the equipment is much easier to maintain than, say, a Mellotron. The bad news is that the players are pretty low fidelity, and players and media are hard to find.
