    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.

Delete the last 4 chars in the compressed string and watch the ball wobble around like mad
u/tomxor

Yeah -V/8 is for velocity damping on Y. Which is necessary with velocity based collision resolution. An alternative that doesn't require this is verlet integration, but that requires far more characters.

I like this trick of re-using the same args for moveTo and arc back to back. The first two args are x and y for both and moveTo ignores extra args.
u/magna

Text positioning tweaked on a Chrome on macOS, so may look screwed up on other browsers.
u/magna

Also, holy shit. Look at those artifacts around the skunk. Who at Apple cleaned that image?
u/magna

*Apple -> Chrome/Google? I don't know who is responsible for the emojis :)
u/mxfh

Lol. Apple Skunkworks I suppose. dwitter is a whole argument while real other browsers should be enforced to be allowed on iOS.
u/rep_movsd

Chromium doest show the skunk :(
u/tomxor

Safari/webkit is the new IE in terms of browser stagnation and bugs, i come to dwitter to not care about it :)
