We didn't exactly use compute shaders for Chaotica, we used OpenCL instead, which is a more general GPGPU framework like CUDA.
I tried Apophysis (or one of the many spinoffs), but it never quite clicked.
It might not run very well depending on your hardware, though.
We're lurking on Discord these days, there are some new people from Austria sometimes joining our meetups, you should come along :)
Honestly I try not doing much computer stuff in my free time because I'm doing so much in my day to day but I'll stop by some time! I've been in the Chaotica discord for years but never said hello.
