So supposedly no one uses screensavers any more, because LCD/LED screens don't need them and they use more power than just shutting off the screen, but I still do anyway because I like them. I had a Legend of Zelda one that I used for a while until the end of Flash took effect in January 2021. I just switched to Mystify instead, but I always wondered if I could make my own. I wanted a screensaver that rotated every RGB sub-pixel through the 255-0 range and back.
Eventually on a whim in November 2021 I decided to go ahead and learn how to make screensavers, and this is the result.
