    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.

Good colors

Wow
u/Bugsy

Seeing as you probably didn
u/Bugsy

't know, it's not a big deal, but it's generally preferred if you post any remixes as remixes, which can be done by editing the code directly beneath a post

I added a remix link to d/3613 :)
u/GitAtMe

Bugsy is right I couldn’t figure it out, thanks for fixing it sigveseb!!!
u/Xen

it was an obvious accident as the first you posted was a link, its just some past users harvested older dweets and tried to pass them as their own.
