    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.

u/KilledByAPixel

This one was fun because I found a way to combine the loops and hide the start/end gap that removes the need for a beginPath. Freeded up enough space for background color, or something cool in a remix.
u/aleamb

yeah!
u/pavel

Buggy in Safari. Jagged things sticking out, i think from the line end-caps, also breaks after a while because you didn't wrap-around the angle in arc.
u/pavel

Huh, actually both issues are resolved by modding the arc angle by 2*pi

u/pavel

Looks like the code you started with used Math.random at each step which made the ultimate position of each square at time 't' impossible to determine directly. Switching to instead use any function of just t makes it quite simple so there is no need to initialize stuff at time 0 and keep it updated.

I learned that in d/11421 to save chars and make d/11424

great. thanks very much

In my head I was thinking also that t*97%11 is a pseudo-random generator...
