    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 is a browser glitch, right? It only looks cool because the browser starts using too few segments to draw the spiral. Would be boring in a fixed browser.
u/Haabilo

@sparr Not really a glitch. The code uses lineTo as means to straw the lines. It also sets the maximum amount 5
u/Haabilo

Of you let it run long enough it returns to the original image but sort of pixelated and a little more and it'll return to the original image
