    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.

Sweet!

very nice
u/gambit

hi im new! can you explain me "c.width|=0" what does it do? thanks
u/DataMeta

Welcome! It's a shorter way of clearing canvas pixels/state. Can be chained like so: for(c.width|=n=i=256;i--;). It can't be done here because we must clear the canvas before scaling it
