    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.

Semi-Transparent Colored Squares

u/LimeLaser

I tried to get a decent rectangular-color-fill distribution by allowing negative widths and heights.
u/joeytwiddle

Ah nice approach, to avoid the top and left edges feeling lonely

Ordered Dithering Of Red-Green Gradient

u/LimeLaser

Simulates a 6-bit-per-channel color scheme. The "d" variable represents an entry in a Bayer matrix; setting d=0 will show non-dithered 6-bit-per-channel gradient.
