    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.

Nice! although i think technically crystaline makes it quartz; glass is amorphous but I no idea how that would look.

I would love to find a better / shorter 1D noise function #challenge

u/pavel

This one assigns a 'random' number to each integer k via S(k*k) and uses smoothstep to interpolate between them.
u/pavel

Another idea to play around with f=(i,n=9)=>n&&C(n**.5*i)/n+f(i,n-1)
