be8ca2ec | 499 | * Two spinning wheels, basically XORed together, with a color palette that should |
500 | * be pretty easy to switch around. Timed to the beat; also introduces "clickiness" | |
501 | * which makes the movement non-linear throughout a given beat, giving it a nice | |
502 | * dance feel. I'm not 100% sure that it's actually going to look like it's _on_ | |
503 | * the beat, but that should be easy enough to adjust. | |
504 | * | |
505 | * It's particularly nice to turn down the clickiness and turn up derez during | |
506 | * slow/beatless parts of the music and then revert them at the drop :) But maybe | |
507 | * I shouldn't be listening to so much shitty dubstep while making these... | |
