    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 supposed to be water in the sun, but i couldn't figure out how to make the color blue instead of rainbow without ruining the shine.. any ideas?

c.width=w=70;for(i=2800;i--;)x.fillRect(X=i%w,Y=i/w,X/9+1*(Y/7)+S(X/7-5*t),1),x.fillStyle=hsl(${U=191+i/55+S(t*9+i)*4},60%,40%,${T(U)+.5}
u/danny@hille.dk

You can do it the lazy way, by simply adjusting the number range to lay within a single color hue, and shifting it towards the blue hue, blue is around 165 (light greenish blue) to 260(purplish blue)
u/danny@hille.dk

But i actually like the rainbow water better :-)
