    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.

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.

Hollow and somewhat damaged Menger sponge

"You will be assimilated. Resistance is futile." (comes up in my mind when I see it)
u/UEZ

Well done. Looks very nice. Can somebody explain me what this is about: [a,b,z]=x[q]||[0,0,6.3]. I assume it has something to do with arrays... Thx :-)
u/tomxor

It's called destructuring. The right hand side simply evaluates to an array (x[q] or [0,0,6.3] is x[q] is falsey). Then the elements of this array are assigned to variable names based on positions on the left, e.g a=0, b=0, z=6.3. Note that the left hand side is syntactic sugar, it's not an array literal.
u/UEZ

@tomxor: thx for your explanation. :-)
