    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.

you can see this concept implemented without compression in d/9676

u/BirdsTweetCodersDweet: that helps, but I really wanted to keep the centered display. See my remix where I use a single for loop to jump around the grid randomly, which avoids the random initialization of k.

it should be possible to optimize the modular inversion and exponentiation, but it would probably go over the character limit
