Life in Life: Using something called an OTCA metapixel (Outer Totalistic Cellular Automata Meta-Pixel), which is a pattern in Conway’s Game of Life, someone has implemented the Game of Life inside of another Game of Life.

More on the OTCA metapixel.

Neat! Needs a 'meta' tag ...

People mention games being Turing complete, but the complexity is usually such so that we never actually see the completeness being made. Surely it's been done before? But this is definitely the first time I've actually seen it. Very awesome.

Oh I see that the OCTA metapixel needs ~35k generations to turn on or off. I wonder how many generations were run to make this video. That's a whole lot of base pixels in the end result as well.

Are people still making those Xzibit jokes?

The nice thing about the OCTA metapixel (which was created more than 6 years ago) is there's a hell of a lot of repetition. So it runs super super super fast under a hashlife-like implementation.

Oh shoot, I thought Turing Complete only meant it can 100% emulate itself. woops.

"Great fleas have little fleas upon their backs to bite 'em,
And little fleas have lesser fleas, and so ad infinitum.
And the great fleas themselves, in turn, have greater fleas to go on,
While these again have greater still, and greater still, and so on."

I believe this was linked to in a related thread about Minecraft in Minecraft

Great!

Now do Minecraft.

But they can they implement this?

This takes me back to the moment when I stopped playing The Sims.

I was playing a game in which a similar version of myself was playing a game. My sim was sitting in his house alone playing a computer game in an attempt to improve mood stats. The meta of this, exploded my mind and I vowed to stop playing games of this type forever.

Rather than watching the video on YouTube, install the program "golly" and play with this stuff yourself! Remember, Life should be an ACTIVE pursuit, not a passive one.

Next someone needs to implement Life on this Turing machine.

Nice, the zoom out to see all the packets(?) racing around was like something from Tron.

SPOILER ALERT, surely.

Saw this a bit ago. I love it. Game of Life projects are always fascinating.

I liked the use of the endlessly ascending tone for thematic reasons, but it's actually kind of a painful noise.

ahhhh, awesome :)

The slow zoom out is a really cool presentation; lets you appreciate the scale.

But now I want to start randomly flipping individual squares and see how robust it is. Will it repair itself, create a 'dead pixel', or will the damage spread over the whole organism?

benito: the structure is pretty delicate. if you perturb it, unless your perturbation is just adding a cell that dies out immediately, you will wreak havoc with the whole thing. but it's quite interesting to watch the damage spread out. as i posted above: install "golly" and you can play with this yourself, rather than just passively watching on YouTube (the OTCA is in the bundled Golly pattern library, as well as tons of other neat stuff).

crazy_yeti is right, these kinds of structures tend not to be self-repairing. And yes, golly is wonderful.

Huh, I was digging for this just the other day 'cause I wanted to post it on /r/whoadude.

Is this an inverse fractal?
posted by fredludd at 11:14 AM on May 23, 2012


I think that's the same as a fractal.

That is it! It's over! There is nothing left to accomplish. We can just beam this into space and the aliens will say, "ah, the humans have arrived!" We are THROUGH THE FUCKING LOOKING GLASS.
