    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.

Hi there what is this part doing a=w*!x. ? :)
u/BalintCsala

@alien I think that gets the image data at the current position and if it's red, makes the fillStyle black and vice-versa
u/nabbydude

@alien @BalintCsala is right, x.blahblah is 0 if the pixel is black and 255 if its red, inverting it makes 0 into 1 and 255 into 0, and then we multiply by w because its a big number (>255) to make the color more visible

Proof-of-concept of using valueOf to prevent function call parenthesis (()) to save space when a function is used at least 5 times.
