    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.

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}%)

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

Just some interference patterns, a first scribble :)

You've reached the end.
