    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

Seriously, it's like 30x faster, this is going to be my test case for fixing Dwitter perf
u/KilledByAPixel

Wow! 🤯 Runs great in capjs ;) Though I did need to disable loop protect to get the full render.

u/tomxor

Woooo perf fixes are merged! :D Big shout out to u/LionLeaf and u/KilledByAPixel for working through this with me. Keep an eye out for issues and let us know on discord if you spot any regressions.

cool idea
u/KilledByAPixel

Reload to make new art, it may take a few tries to get something good!
u/DataMeta

Sometimes it takes a while or looks like it is gone then comes back, I use some extra code to speed it up!
