Satori is a screensaver for OS X that creates flowing, meditative images based on various mathematical formulae.
Version 2.0 is compatible with OS X 10.9 and 10.10 (and should run on later OS X releases as well). Satori uses six different mathematical formulas in many combinations, to produce a staggering variety of images. The images Satori makes aren't just still frames; they animate continuously, flowing and oozing color. It's impossible to describe; it has to be seen. Satori was originally written in 1990, about 25 years ago. It became a part of the After Dark screensaver package produced by Berkeley Systems, along with Rose and many other modules. After Dark is only a distant memory now, but in collaboration with Infinisys Ltd., I've revived Satori to run again.
