    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.

#default reflected in rippling #water (night, redux)

u/joeytwiddle

This is more efficient than fillRect() but it's too long! c.width|=c.style.filter='invert(100%)' (This way, we also need to change clearRect into fillRect)
u/magna

c.style.filter='invert(' suffices since browsers are notoriously forgiving
