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.

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