    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.

This is very heavy on my laptop! Remixed here: #4841
u/joeytwiddle

Very nice though. It plays tricks on my eyes, seems to be always growing.

Sometimes dwitts gets heavy here also scrolling down the list.. most times it help to copy the share link and look at it alone, but yea this one can be heavy, running lots of filters and "gCO"'s

I was first thinking of doing alot of 3d rotating boxes but didnt find any good,,, ;) then I thought of reading pixels as letters and do all code I need on the picture but code got to long,, so a simple animation will do.

ah yea, I didnt think about zooming ;) try this code k=c.width=1920;x.rotate(t);for(j=26;j--;){for(i=20;i--;){b=300+S(t)*150;a=b*2;x.fillRect(-a*6+i*a+S(t)*k%a+(j*b)%a,-a*6+j*b+C(t)*k%a,b,b)}}
