    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.

🐜 Langton's ant (he is turing-complete :) The idea is to use canvas buffer as data storage. Let's try to implement Game of Life, guys?

This is an experiment. if you #waitforit , look at the FPS. It will turn into a log function

there is nothing to see! maybe you meant to not clear the canvas? try removing c.width|=

It's a little faint, but I can see it breathing
u/magna

What browser y'all using? I see it with chrome both on mac and win.
u/tomxor

I can see it on Linux using Firefox@30 FPS and Chrome@15 FPS. I suspect on a phone it's going to be single digits with Chrome so it's going to take a whlie to appear.

I'm using Firepants on a BlackberryPi in 2076, looks fine here
