    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.

mathematically correct sine rainbow, replace p with 2 for approximate, but more compact, sine rainbow

dang I forgot the 0.5 on 127
u/dragon7076

it's mathematically correct ¯\_(ツ)_/¯
u/dragon7076

it's not*

o=127.5 p=Math.PI*2/3 c.style.background=R(o+o*S(t),o+o*S(t-p),o+o*S(t+p)) - you don't need to fill the entire screen to set a background ;)

Oh I understand now what's this

btw Math.PI*2/3 is about 2.094 so you can just remove the P line and replace P with 2 and get the same effect, saving 14 bytes.
