    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.

Tiny tweak, using the fact that x.l=translate,l(...),l(...) saves two characters. This is the equivalent of x[l='translate'](...),x[l](...) if you're already using with(x).

using ellipse() and lots of trig to draw dots on the surface of a #sphere

u/f8f82804

it takes 154 to center the sphere: for(i=c.width^=0;i--;x.beginPath(x.fill()))C(a=t-i)>0&&x.ellipse(960+(X=(i*960-i*i)**.5*S(a)),60+i,9*C(a)*(1-((b=i-480)/480)**2)**.5,9,Math.atan(b/X),0,7)

Very clever mini dithers! How about dithering a sphere?
u/f8f82804

A sphere is a good idea! I'm still trying to work on spatial coherence though; see my earlier Floyd-Steinberg demo to get an idea of what's possible with 2d error diffusion. This dweet is a start at using a mask instead of diffusing errors.
