    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.

If I'm being honest, I have *no clue* what I did here, but it looks cool, so I'm posting the remix anyways

Similar to my previous post, of a water-like texture, but with tons of lines instead :P (re-upload - fixed errors)

A water or metal-like texture I found while experimenting with expanding circles. Looks pretty neat apart from that pesky horizontal line to the right :D
