    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.

For a more old school feeling, replace 4*t with 4*t|0
u/sigveseb

Nice colors, reminds me of the gameboy color palette.
u/sigveseb

(Did you delete an older version of this dweet?)
u/iverjo

Yes, I deleted the old school version that quantized the colors with 4*t|0 and put it as a comment instead :)
u/sigveseb

Ok, that was was the one I meant to comment on about the gameboy color palette ^^
u/iverjo

Does it deserve to be a separate dweet?
u/sigveseb

The more the merrier :P
u/iverjo

Ok, sure :P

Whoa! When I was younger I used to have nightmares about this damn thing. I would clean it all away but then it would come creeping back. Weird that you found it in 2016!
