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?
