    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.

-11 bytes: Eliminated the intermediate k, moved some coefficients around, and swapped hypot for square values which is actually more stable for intersection resolution. Now it will never stop jiggling :D

Currently traced pixel is part of the ball and part of the background therefore collision. Awesome trick. My first time seeing this.

One trick here is f();g();h(-1,-1) is the same as h(~f(),~g()) when f and g return a falsy value, undefined in this case.
u/pavel

Notice how none of the distance variables are based on time, only angles are, yet the distances are changing and nothing is rotating...
u/pavel

Try making the moving a little faster :)

After I wrote this I looked for other dweets using a similar technique and this is the earliest one I've found, and it includes an explanation d/10212
u/KilledByAPixel

Amazing work! I have not seen the ~ before, will be using it a lot now. I tried to explain the 60*t trick in one of my blog posts, https://frankforce.com/?p=7160
u/pavel

That is an amazingly detailed explanation with great visual aids.
u/pavel

To clarify your explanation, any integer time works. 60*t is naturally an integer (ish). frame is one char longer without numerical errors. In general, (n*t|0) works for any n.
