    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.

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
u/andrea270872

great. thanks very much

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

Satisfying

I haven't actually put the time into understanding how this works, but that doesn't stop me from remixing it!
