Amending this with the youtube examples because they're damned impressive:
My binary operator lore is weak. I don't get things like t>>13 (t is just 8 bits right? why shift it 13 digits?)

µB: t is an int, 32 or 64 bits or so. The clever thing here is that they define t as the argument to main, which shaves away a few bytes of source code (Normally int t; or so). putchar also takes an int, but as far as I understand it, it truncates the output to 8 bits, which is what gets sent to stdout and then into /dev/audio.
This is really a form of extended linear feedback shift register, a bit like, you guessed it, shitwave. And this might serve as inspiration for a new version of just that in the future.

Ah, ok. I was assuming that t is a char, and auto-truncates each time it exceeds 255. Is the binary shift circular in C?

Not circular. That operation is actually usually called a rotation.

awesome! i have no idea how it works but these examples sure are impressive.

I understand how this works, but it impresses me a lot anyway.

Forgive me but would someone be sweet enough to really dumb this down for me and explain it like im 5? It sounds awesome but I feel I am missing a bit of the awesome due to lack of background knowledge.

I'm dumb too, but it seems you are running a simple math program in c, and sending the output to the audio device directly where it is interpreted as rhythmic audio.

Very nice! The outcome sounds similar to connecting together certain logic chips in a simple pattern.
