I have seen it before, pretty trippy!
Wish I could see the source code for that. . . .

Oh yeah, I’ve seen that before too. As a matter of fact, I believe it was David who posted a link that shows you how it was done. That link is burried deep inside Random somewhere, I’m too lazy to look for it. :-\

Ah…, the answer is always divisible by 9. By placing the same symbol on all multiples of 9 (0,9,18,27… etc) it seems like it is reading your mind. Very clever, and the symbol changes each time. No need for source code really, just need to know how to change the symbols each time around.
