    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.

donut #sdf

u/vgel

this one was a huge pain to make fit even with the compression, I'll be really impressed if someone can golf it down to fit in 140 characters
u/vgel

I finally was able to, by sacrificing some of the visuals: d/27314
u/tomxor

Nice! I'm interested to dig into this in SDF form
u/magna

Amazin!

dithered donut #sdf

u/vgel

got inspired by d/16174 for some ways to shrink it further :-)
u/Xen

shaved a few: for(w=p=c.width|=H=Math.hypot;p+=279,X=(Q=p%w)/1e3-1,p<2e6;x.fillRect(Q,W,s=60/i,s))for(Z=i=D=1;++i<9&D>.1;)Z-=D=H((H((C(t)*X-S(t)*Z),(W=p/w)/500-1)-.4),(C(t)*Z+S(t)*X))-.1
u/joeytwiddle
