You know me - if there's a way to use mathematics to produce trippy

Well, I suspect I'm doomed to fail either way, but hey! :-P

The hard part is FINDING THIS EQUATION! >_<

I've found several sites about this stuff, but none of them present a 
formula I can comprehend. Now that I have a working formula and I know 
what all the variables are supposed to be, I stand a chance...
