Fractal generator

Andrei Kashcha has created a lovely fractal generator, using WebGPL.

Click "Randomize" to have it generate a new fractal. If you want, tinker with some of the parameters by changing values in the function, and watch as it produces trippy results! (Deeper instructions by Kashcha here, along with the code.)

I've been sitting here in a trance staring at this thing for half an hour now, somebody help me.
