    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.

didn't realise very obvious character saving so made it look a bit nicer

u/Xen

yup, still some golf on this one,.. but also it has a nice style, join discord dwitter chat if you wish and we can crush this all the way down so you can build it back up and add more ;), come shout me.

I'll consider that when I have some spare time on my hands!

Boing. This took me longer to make than I'd like to admit lol

Yeah you had to position it to undo the rotate. Non-trivial!

Updated with better colours and way to change the speed, standard of .5; still counts weird but that's okay

had to do t^1 instead of Math.Round cuz character limit so it counts weirdly but does go through all of them
