    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.

Black Hole

u/pavel

Deleting %(2*Math.PI) works in Chrome but not in Safari.
u/pavel

Notice that the radius does not change with time. The inward motion is achieved by drawing a smaller radius square next to where the larger radius square was a frame ago.
u/pavel

If the squares were numbered you'd see that the numbers jump around every frame.
