    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.

u/fentbiggesthater

couldve sworn ive seen this somewhere before also, stolen? impressive
u/New_Core

Nah, its not stolen.. but its a remix of the one zachygreen did.. I made it in a different way but I posted it as a remix of his since its so alike looking.. If you mean you seen it even before that then there is always that chance someone made something simular before.. who knows ;)
u/lewdev

I totally saw this on StarFox on SNES! 😉
