    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.

Plays random cellular automata

u/Odog8

im thinking about using substr
u/joeytwiddle

Why not run them in order? Are the early ones boring? Maybe boring for someone quite familiar with them.
u/Odog8

Kind of, a lot are just straight lines when starting from a single cell at the start
u/Odog8

Also more fun this way ;)
u/joeytwiddle

Understood!

my TP stash !

u/pavel

To get (X,Y) out of n you do (n%width,n/width|0). Here n=60*t and you got 21 TPs across so x.font='90px"';x.fillText('🧻',60*t%21*90,(60*t/21|0)*90)
u/pavel

This reveals that if we pick n=63*t we can shorten Y=63*t/21|0=3*t|0
u/Odog8

Thanks!
