    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.

@joeytwiddle yours looks much more like it! I had a few other versions with fBm and fill etc. but couldn't get them under 140 chars!

I used a different strategy for the transform and managed to salvage enough characters to animate it.

This is the best I could manage in 140 character. I had a this but could not shrink it: c.width|=0 for(i=9;i--;)for(j=9;j--;)[0,2,4].map(d=>x.fillRect(0,0,2,2,x.fillStyle=R(d*99),a=[20,-9,0,h=99+30*S(i+j+t),-20,-9],a.splice(d,2),x.setTransform(...a,(24+i-j)*40,(39-i-j)*18-h)))

u/snydej

Correction: c.width|=0;for(i=9;i--;)for(j=9;j--;)[0,2,4].map(d=>x.fillRect(0,0,2,2,x.fillStyle=R(d*99),a=[20,-9,0,h=99+30*S(i+j+t),-20,-9],a.splice(d,2),x.setTransform(...a,(24+i-j)*40,(39-i-j)*18-h)))
