    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.

wanted to use (1+S(t)*C(t)) instead of (1+C(t)) but oh well

u/magna

Shaved you some characters and added the +S(t): d/10329

In 139, with a few compromises: with(x)for(r=Math.random,i=k=512;i-=32;beginPath(arc(704+k*r(),284+k*r(),i+i*S(t)*C(t),0,7),fill()))fillStyle=?hsla(${t*99+i},99%,50%,.01)?

Hm, Unexpected token ?
u/Purpzie

Managed to shorten it to with(x)for(r=Math.random,i=32;i--;beginPath(arc(r()*500+750,r()*500+300,i*9+i*9*S(t)*C(t),0,9),fill()))fillStyle=hsla(${t*99+i*9},99%,50%,.01)
