    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.

i will retire this experiment now. the concept looked much neater in my head before trying it : /

i would really appreciate if anyone can reference any similar dweets : )

Uncompressed code is 156/140 so i got rid of the background "pixel grid" shown here to get the original d/20295 under 140 ... still looking to golf some more...

c.width|=0,m=0|(4+100*S(t/4)**2),s=1920/m;for(k=m*m;a=[u=k%m*s,v=(k/m|0)*s,s,s],l=v-T(t)*(u-960)-540+2*s,k--;)s<l&&l<2*s?x.fillRect(...a):x.strokeRect(...a)
u/smtsjhr

all i did to get under 140 was remove x.strokeRect(...a)
u/smtsjhr

in need of a better way to alternate between x.stroke and x.fill as the loop ranges over the rectangles of the grid
