    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.

I tried making the values for the deviation between pi and the replay speed as accurate as possible to prevent desynchronization (pi / 3.66 = .8583586585218014)
u/username

you can save a lot of bytes by playing at roughly pi sped up (d/14496)
