    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.

NO NOT UNCOMMENT UNLESS YOU'RE USING CHROME!! ...It crashes Firefox... I didn't want to do more obfuscation but found no way here... for(t%4<(x.globalAlpha=.1)?w=c.width^=0:(x.fillRect(0,0,w,w),n=w*t^7,x.globalCompositeOperation='overlay'),i=2e3;i--;)x.fillStyle=R(0,i%3?255:0),x.fillRect(S(n++|i)*w%w,i%w,90,90); Change the 7 in n=w*t^7 or 4 in i%4?255 for different growth patterns.

Fun! #interactive

There's a difference between Chrome/Firefox on both linux and windows. This should be seen as a lingering webbing line. Investigating...

Good technique here - https://www.dwitter.net/d/7801 need to switch over t==0 to !t ... fail
