    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.

@pavel, if you ever find that you just can't get it working within 140b, you have 2 options, the handy compressor @ d/9207, or there's also https://codegolf.tk which allows up to 1kb with bonus cred for getting under 512 or 140.. full disclosure, i run codegolf.tk. brilliant work btw. :)

u/prplz

third option: keep trying all day
u/cantelope

@prplz, of course. how stupid of me. obviously i was advocating giving up easily.

Nice! There is some flicker but you saved enough bytes to fix p=i=>99*[0,0,3-i,1,6-i,2,i-5,i-7][~~i];for(c.width|=i=8,x.rotate(7),T=8*t%8;i--;m+7&7&&x.fillRect(p(m?i:T)+450,p(m?6-i&7:8-T),90,90))m=~~T-i

This was fun. I also tried two totally different implementations but it seems your approach is the best.
