    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.

Yes! That's exactly what I originally wanted to do! (but i'm more stupid lol) Nice done!

Rotating pyramid. Can anyone figure out how to make the colors smoothly darken so that it loops perfectly?

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.
