r/cellular_automata

I like to watch and think about the mechanics of how they work. Almost like little cars or spaceships.

It's not really a background color, but just the cell state that appears to be the background in this CA. It's interesting how much it looks like it's just 2D automata, but it's just that one single layer pressed up against the boundaries, since the simulation is cyclical (meaning all sides of the world connect).

I'm still working on this 3D version of Slide Rules, but I've got better rendering going on. Try:

Basically, this game I'm making "CA-REAPER" would have the player, made up of cells, trying to escape from the main Cellular Automaton. The one seen in the video is known as "Star Wars", and is one of my favourite because it kinda looks like a factory. The player would go around the CA, collecting guns that the CA itself creates- when its cells develop into a shape, that shape detaches and becomes a gun that the player can pick up that when shot, makes all cells in a radius of the impact point become a localized cellular automaton defined by the procedurally generated gun. The main CA could also generate enemies this way... idk, just seems like an interesting idea for an extraction shooter

I'm excited to finally try this, and what I've found is that it's much harder to get interesting phenomena to happen out of random values, but I'm betting on them being very profound when discovered. I had to make some control modifications, like extending the neighbor counts up to 26 instead of 8, and making a 3D control for the ignore directions. I've also allowed it to load the 2D Slide Rules automata, but the neighbor counts and ignore directions are toggled off past 8, and in most cases the reactions are stagnated, though it can often be reinvigorated by toggling more neighbor counts and ignore directions past 8.

There's still some development to be done, and also looking for advice from those who have made 3D automata. You can currently choose a fully transparent color, but it's crudely implemented. I also don't really have any depth or advanced shading depicted. I'll have to look at ways to do that an consider the costs to performance.

I was playing around studying Game of Life patterns and found a fun way to visualize DNA. I learned the oscillators and glider eaters from conwaylife.com/book. I remember from the low weight spaceship gun that sparks from these oscillators can be used to destroy spaceships if they're placed correctly, so I made the Trojan horse.

I have been working on this for way longer than I want to admit, and the learning curve has been pretty crazy. But I finally feel its in an ok enough state to show you guys, here, on these hallowed grounds.

Its called CYMATA (cymatics + cellualar automata) and its built for touchscreens. Ive been messing around with CA for years now and I have been using it so much in my music visuals it was sort of becoming addictive. There was something about watching it change with the music that tickled the brain in such a good way. I dont think Im an ASMR guy but thats probably the best analogy: ASMR for the eyballs.

And about a year ago I bought a new LG TV, and the screensavers were disappointingly BAD. So I had the idea to try to put my music visuals into an app. CA can just keep going forever and we will never see the same pattern twice.

Anyway, about the features:

Its basically a trippy VJ toy for handheld iOS devices, or runs independently on tvOS

• it works independently on tvos with Siri remote too, (iphones turn into a remote to paint on tvos with your ios device)
• has a built in player for Apple Music, Soundcloud and radio
• 12 channel audio analysis
• Audio reactive drum pad for Tibetan bowls and handpan for healing frequencies
• Clock and message display
• Record Screen in/out
• Unique glitch camera feature (camera CA glitching!)
• ASCII, dither, 3D and a bunch of effects
• Customized brushes including sprite brush
• A growing collection of paintable shaders
• And a bunch of other useless stuff you dont need.

Originally I released it with a free tier, long story short it wasnt sustainable. So Im charging subscription model to keep the online audio analysis working.

There is a FREE trial for the first week, if you're not feeling it you can cancel any time.

• The price is $19.99 for yearly subscription
• Or if you prefer to go monthly : $7.99

I really hope you can get something out of this! I feels a bit like preaching to the choir here, I'm very nervous to hear what you think! I started an instagram that is growing steadily since I have started posting regularly.

Let me know if you have any suggestions for shaders or ways to improve the app.

Cheers,

Nevertek

I take a look at this one for a long time then brief walk around to look at some others

This ruleset ends up creating a spacetime pattern somewhat reminiscent of bubbling quantum fluctuations in vacuum

Interestingly, in this model, when a vaccine policy is implemented loosely it kind of makes the outbreak worse, only very strict vaccine policies are truly better than no vaccination at all.

this does not take overwhelmed haalthcare systems into account, so obviously reality is far more complex than this.

Full credit to Nicholas Carlini for designing light weight spaceship logic gates, otherwise this video wouldn't be possible. You can find more about it on his writing "Improved Logic Gates on Conway's Game of Life - Part 3": https://nicholas.carlini.com/writing/2021/improved-logic-gates-game-of-life.html. He has even made fully functional computers which is something I could dream of. This was actually my first time building anything in Conway's Game of Life, I first read all his essays on Game of Life computers before starting.

I recreated his logic gates pixel by pixel and copied his rotation gates to reroute I/O. Synced everything by analyzing needed distance + specific generations that the components worked on which was a fun nightmare. The shapes are made with 4x4 still lives.

(I added the "I/O routing by me" to say that Nicholas Carlini didn't build his logic gates this way, they were made with efficiency in mind.)

The song used in this video is called Altros by ARForest and it has a very beautiful music video by inukoro. (It's on youtube: https://youtu.be/LvIsvi6fVlk)

Turned my highly optimized Hex CA engine into an npm package so anyone can build high performance CAs to simulate physical systems. Just ask your AI coding agent to use @hexlife/embed to build you a simulation and they will have the best tools to quickly build something.

To demonstrate this i built a couple of simulations entirely with this library and I will showcase them here over the next days.

Today I'm showing you the Wildfire simulation, you can try it out yourself here https://sidem.github.io/HexLife/wildfire-command.html
