which evolves and it just moves at a certain direction.
That's like this vortex rings.
This is an analogy.
The Game of Life is a discrete equation and the fluid Navier-Stokes is a continuous equation, but mathematically, they have some similar features.
And so all the time people discovered more and more interesting things that you could build within the game of life.
The game of life is a very simple system.
It only has like three or four rules to do it.
But you can design all kinds of interesting configurations inside it.
There's something called a glider gun that does nothing but spit out gliders one at a time.
And then after a lot of effort, people managed to create AND gates and OR gates for gliders.
Like there's this massive, ridiculous structure, which if you have a stream of gliders coming in here and a stream of gliders coming in here, then you may produce extreme gliders coming out.
If both of the streams have gliders, then there'll be an output stream.
But if only one of them does, then nothing comes out.
So they could build something like that.
And once you could build these basic gates, then just from software engineering, you can build almost anything.
You can build a Turing machine.
I mean, it's like an enormous steampunk type things.
They look ridiculous, but then people also generated self-replicating objects in the game of life.
A massive machine, a binomial machine, which over a huge period of time, and it always looked like glider guns inside doing these very steampunk calculations, it would create another version of itself,
which could replicate.
