    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! beat me to it, although i'm doing something slightly different... progressing at a rate of -4 chars per day :P

This grid takes about 850 generations to stabilize between 2 states! "Theoretically, Conway's Life has the power of a universal Turing machine: anything that can be computed algorithmically can be computed within Life."

Clicking tags I realized the sheer number of cool #gameoflife dweets of times yore. 😲

Yup, some of the oldest ones from 2017 are quite impressive and completely ucompressed, although that tag is a bit polluted with serpinski triangles later on.
