what equaation was used?

@Gad Not positive, but I think it was something like this: R=SIN(30*(X+0.2*SIN(20*Y))) G=0 B=-SIN(30*(X+0.2*SIN(20*Y)))

i got an error...

@Gad: Are you positive you entered it correctly? It worked for me, except I got one of the numbers wrong, so it turned out different from the picture I submitted. Even then, it wouldn't give that error; the result would just look different. By the way, to get something more like the original, try replacing both 0.2's with 0.01.

is there a difference between dash and minus?

@Gad: I don't think so. It's on the main page of the keyboard, and it's not the underscore.
