    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.

Rorschach test - I see: klaatu greeted by humans
u/taupelink

it is kind of rorschach-like, isn't it? yeah, i tried to make the humanoid shapes more prominent but couldn't get there. i settled for this abstract pattern...i had spring|fall in mind when i did the colors

Now this is my new background, this technique of yours, is capable of rendering some fantastic artistic images r=Math.random;for(i=k=119;i--;x.fillRect(k*X,k*Y,i/t,i/t))X=r(Y=r()*11)*21,h=k*S(C(Y*S(p=X-X*X/71)|p*C(Y))*Y)+i,x.fillStyle=R(h*X/8,h*Y/4)

Seek admiring fountain at sunset r=Math.random;for(i=k=110;i--;x.fillRect(k*X,k*Y,i/t,i/t))X=r(Y=r()*9)*16,h=k*S(C(Y*S(p=X-X*X/18)|p*C(Y))*Y)+i,x.fillStyle=R(h*X/6,h*Y/9)

cool, enjoy!
