Lines that move with music, Help Options

[Panja4]

A few years ago I used to put a type of code in my pages that when music is played several lines would dance to the music, I cannot remember what the code is called! There was no limit to how many could be stacked together or what colors. I have been racking my brain trying to remember what the specifics of the code was or even what they were called.
At one time I had found a page that had all soets of designs one I remember was a white rabbit. I was usinf WebTV at the time so i don't remember if it was a specific code for WebTV. Any help would be apperciated!

Thanks
