  • tomxor: Finally resorted to UTF8. This is a reasonably accurate slow motion aperture grille scanline animation... Although if run very slow you will see it's not simulating 3 electron beams. t=fps (scanline) w=width (subpixels) the later must be a multiple of 3 and 5. Use X, Y and floored F to plugin your own fractal!
  • tomxor: Uncompressed: w=90,i=l=w*w/5,t=1+t*t/12; for(x.fillRect(0,0,c.width=w*2,w*2);i--;x.fillRect(X*6,Y*6,1+K,5)) X=i%w/3,Y=i/w|0,F=t-i/l,K=1-F%1,K*=(Y^X-~F)/27%1+K**8, x.fillStyle=hsl(${i*120},99%,${K*99}%)
  • sigveseb: Kick-ass!

  • Load older comments...
  • cantelope: I see some gathering of points in the middle of the top and bottom panels, but other than that, a faithful reproduction. kudos!
  • pavel: I use polar coordinates, even though the radius is uniformly random that results in more dots near the middle :/
  • iverjo: #cube #d3

  • katkip: Wow! Amazing
  • robbyg: I was hoping someone would come up with something better to do with that function. Awesome! :)
