    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.

bump mapping remix

u/Joachim

Really nice #lighting
u/@noel

Beautiful. I need to dig into this, to understand how this actually works.
u/rodrigo.siqueira

Wow! Replace X^Y with X|Y to generate Sierpinski triangles. Replace Math.min with Math.max for a more dramatic effect. Remove |0 for improved golfing (a minimal visible effect on top alignment). Replace "t*1.2" with "C(i+t)*6" for the "water effect".
u/jellyedwards

Wow that's amazing!!
