    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.

this stuff would be much cooler if i had a faster machine i think
u/Purpzie

are you saying that WE COULD HAVE DONE c.width|= ON ITS OWN LINE THIS WHOLE TIME INSTEAD OF c.width
u/Purpzie

*c.width|=0
u/magna

That's effectively c.width|=x.stroke()
