Rose is a screensaver for OS X that creates a variety of colorful, swirly animated images based on trigonometry. Version 2.0 is compatible with OS X 10.9 and 10.10 (and should run on later OS X releases as well). Rose was originally written in 1989 or so, more than 25 years ago. It became a part of the After Dark screensaver package produced by Berkeley Systems, along with Satori and many other modules. After Dark is only a distant memory now, but in collaboration with Infinisys Ltd., I've revived Rose to run again.
