HEY CLICK THIS: Belles
And then click the play icon on the left of the controls, near the bottom.

Click the scene to make the controls come back and pick other songs or otherwise screw around. If you load your own music, it works best with the notes available when transposed up to C. The JavaScript console will log which ones were missing when a song finishes. If you really, really dig around, you may realize you can load your own characters into this thing with a bit of JSON and web hosting.

(Yes, Carol of the Bells is in the songlist. I had to transcribe it myself and everything.)

Yeah it's late, but I couldn't do the art over the actual holiday period.
(Flash is dead, long live Flash, but at least this year it's something procedural I could build upon existing libraries to make. Photo is mine from long, long ago.)
