    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.

Fragile, Morphing Fabric (or Paint To Cover Graffiti)

u/Xen

very cool idea

(not graffiti part, thats art)
u/LimeLaser

Sorry, I meant that as a description. My friend said it reminded him of those single-color rectangles of paint they cover graffiti with. I don't know the name for them.

This uses the bezierCurveTo method with different values to see what shapes it can draw.
