    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.

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.

The key is the sourcecode. Nice short way to generate a unique key!

Love it!

In this case, it's better to use c.width=z=1920 (same number of characters) so there will be no blank space at the bottom of the page (most visible in fullscreen mode), or you can also use c.width&=z=2e3
