    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!

    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}%)

    Kick-ass!

    bypassing the character limit I see using unicode escapements and regex u r very clever

  • Remixed on my phone so I didn't clean up unused variables etc. Just wanted to see how this looks with emojis :)

    Hi oldspork! The magic happens with the function charCodeAt. This function gets the numeric value of one character at a time. Since these are UTF-16 characters, you can get 16 bits of information in one character.

    Is there an easy way to make these kinds of things? (specifically how the data for each pixel is stored)
  • u/dsamarin
    String.fromCharCode.apply(null, new Uint16Array(34).map((r) => Math.random()*0xffff))
