    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.

Oh nice! You added forward movement
u/iverjo

Great remix!

u/katkip

instead of that let you can use i=4e3,j=s=0
u/pavel

The let is only there for performance to use up free chars. j and s don't need initializing. But i at 4e3 cant do 60fps without let on my machine.
u/pavel

Can just do i=2e3 if you are remixing and need chars
u/katkip

oh, i understand
u/sigveseb

64x36 20FPS Random Sampling Renderer

u/LimeLaser

My attempt to implement per-pixel rendering at interactive rates. Using a Linear Congruential Generator, the pixels to render are chosen psuedo-randomly. It takes 3 frames to render all 2304 pixels, so the actual FPS is 20.

u/ivylab

I don't even ... this is so cool, like a forest
u/pavel

This thing ((i&2)-1)*(2+i%7) takes so many characters. If somebody can figure out a shorter way to generate random-ish positive and negative numbers that aren't too close to zero that would be awesome. 7*C(i) is almost perfect but gets close to zero so you'd have trees on the path.
u/pavel

Oh! 3/C(i) works well here, but has no bound which will be an issue in other contexts.
