M-BUS

There's definitely some scope with data-over-CD-changer-protocol. You've got disc number, track number, time elapsed. Bonus points if you drive a CD changer full of discs where each track on each disc is a different n-bit symbol, perhaps encoded as a DTMF tone or something. Wouldn't be very pleasant to listen to, but it would be slow as hell (and that's kinda the point).

Oh Raspberry Pi, you spoil me with your multitude of interfaces: I2C, SPI, UART, HDMI, Composite - all ripe for abuse.

How about driving a CD changer containing a disc where each track was a different tone. You could definitely get a couple of bits per second out of that (say 2 seconds per track, 16 tracks).

Also, floppy disk music is awesome. I want to see some of that in action. And QuadCopters playing the piano are pretty neat too.

I wonder how finely you could adjust the brightness on an LCD and have it detected by a webcam?
