random atari 8-bit geekery lives on!

for anyone with access to an atari 8-bit computer (or emulator):
A POKE CHEER

Here's something you probably didn't know was tucked away inside your Atari.

10 S=53760:POKE S,230:POKE S+1,175:POKE S+2,231:POKE S+3,175:POKE S+4,229:POKE S+15,3
20 FOR X=0 TO 255.49 STEP 0.135:POKE S+8,X:NEXT X:GOTO 20

try it, it's fun. i remember being impressed back then, and i'm still impressed by this bit of silliness.

EDIT: for those lacking a real atari 8-bit or emulator (thanks to [info]jerronimo:
check out an mp3 i encoded. it loops like that until the program is killed. the click-click-click-click at the start is me typing "run" after i started the recording. the extended wave at the end is because sound output locks up in Atari800X on the mac when the menubar is accessed. the output seems occasionally choppy because it was real-time sound synthesis done in BASIC, on a motorola 6502 running at 1.79 MHz. it's not just the emulator, it sounded choppy on the real thing too. good demo, eh?

for those of us without access to an atari, or an emulator... what does it do?
