    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.

I'm wondering if its is possible to make it look like a honeycomb
u/danny@hille.dk

not a honeycomb - but interesting: for(X=480;X--;x.fillStyle=R(g=X*C(S(t+X/3)+t+S(X/(6+S(X/99+t)))),g*.7))x.fillRect(X*4,0,4,4) x.drawImage(c,0,4)//,1920+(o=9),1080+o) remove ")//" to enable "3d'ish mode" :-)

Looks like snakeskin at a glance. #texture #organic
