    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.

Accidentally created an optical illusion. Watch it for a while, then pause it (scrolling a bit can do this on dwitter), and it will appear to continue to move.

u/BriSeven

another part of this that interests me is that it appears to have a kind of lighting effect that changes as it rotates, but as I built the cubes up in layers of alternating colors, the lighting effect comes accidentally from the way the layers move further and closer apart as the rotate.
