For the Amiga, there was the "Video Backup System":

It was an "ingenious" hack in that it generated a monochrome video signal that
was a valid(-ish) serial stream could be hard-clipped and fed back in through
the serial port. I've never seen it work successfully though.

In a similar vein of misusing the interpretation of signals to produce cute
effects, I offer this which I discovered last night:

Now, there are a number of vector demos which run on oscilloscopes in X-Y mode,
but that one is a bit more special than most in that it's not just some
beam-drawing plus some random music, but a reasonable chiptune that can *also*
be fed into a scope to do vector graphics.

Non-compressed audio can be downloaded from here:

... although I couldn't discern any real difference on my scope between that
and the Vorbis-compressed audio in the Youtube video.
