    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.

One of those things that's difficult to get into 140 chars but doesn't look so impressive hah.

Note that this is done with one stroke. The drawing starts and ends from the point that touches the circle, which changes throughout the animation.

You can see it if you change i/300 to i/310

Would be very cool to see the ball decoupled from the container's reference frame. Could it fit within a compressed dweet?
u/pavel

it is decoupled

Somehow missed that. Awesome.
