    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 love how this might look like the floor is sloping, or it might not. So trippy. It would be nice to avoid that flashy bit at the top though. Maybe in a remix?

Tasteful use of xor!

same effect can be done shorter with x.rect and x.fill('evenodd')
