    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.

High resolution Game of Life with a constant ground layer. It will eventually start cycling. To increase FPS swap 2e4->6e3. To hide the ground swap 4e3->5e3.

u/aleamb

superb!
u/Batrachus

Right now the formula is generating surface points on a coil-like curve. You can get a more ghostly banana by modifying the last two arguments of xfillRect to 5 and the first argument of Math.max to 0.03. You can probably golf this further by drawing circles with radius of M on a simple curve going through the banana's core.
