    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.

You need to write a blog about this particular technique
u/taupelink

i'd like to, but it would take time (i'm a super slow writer) and it's honestly not a priority at the moment. I can at least say this: Part of how I get four vertical bands is having Y range from less than -1 to greater than 1 (in this case, -2 to 2). Multiplying or dividing by Y then has four effects: stretch or compress, do or do not reverse sign
u/rep_movsd

A one page breakdown would be nice, or perhaps I'll write one
u/taupelink

ah ok...like a line-by-line explanation? that's doable...i'll write something up next weekend!

Rorschach test - I see: klaatu greeted by humans
u/taupelink

it is kind of rorschach-like, isn't it? yeah, i tried to make the humanoid shapes more prominent but couldn't get there. i settled for this abstract pattern...i had spring|fall in mind when i did the colors
