    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 does some whack stuff on my desktop Chrome, which you may see if you attempt to edit the code (put a space at the end or something)

u/yokljo

Here is the minimum requirements for the weird Chrome bug to occur: t<.1?w=c.width=100:d=x.getImageData(0,0,w,w);x.putImageData(d,0,0)
