    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.

Nice one. To take it full circle (or square) to d/15628: r=Math.random,a=r(b=r(c=r(l=255))) for(j=576;j--;x.fillStyle=R(a*l,b*l,c*l,r()/5))d=64*r(),z=30-d/2,x.fillRect(j%32*60+z,(j/32|0)*60+z,d,d)

Mellow: r=()=>(1+S(j**5-t++*3))/2 Darker: r=()=>S(j*j-t++*3)%1
