I like to think of this idea of transfer of information (via words, let's say) from speaker/writer to listener/reader, as actually a fairly normal signal processing situation. One where the constructor of the message during it's 'rasterisation' from continuous thoughts to discrete words, can do the job well (ie: band-limit and 'antialias' the message, fully considering the target sampling domain), or badly (ignore the target domain and just speak/write from the source context, leading to 'aliasing' in the listener's received message).
I know this isn't how many people think about words, but I think the idea of antialiasing is relevant and something that people should think more about (including with respect to AI-generated text).

Such a classic sound! Reminds me of the similarly brilliant Star Control II soundtrack (which was also tracker music)!
Reaction-diffusion can definitely do complex life-like behaviour and plenty of other fascinating things! (Rob Munafo's Uskate-World being a great example!) And here's a YT vid of an experimental RD sim that I made a while back to illustrate:
I love the idea of mechanical sensing too! Would be cool if somehow the 3-neighbour 'grow' rule could somehow involve budding off a cell from the (or one of the?) 'parents' and transitions from 1 to 0 (cell death) could actually involve the disassembly of something! : )
Since GOL doesn't consider the self-cell, there are 9 possible values for the 'total' (0 to 8), and since there's both Birth and Survival, that's 18 bits in total, so 2^18 which comes to 262,144 possible rules! That is a LOT more than I thought there were! Cool! - makes me want to explore them again more thoroughly.
I agree individual humans mostly seem to behave more like single-celled micro-organisms and it's a stretch to call it a collective-organism, but it's also not impossible to see the relevant analogous aspects though I think! (like, the internet could be one example?)
It's an interesting question whether the human species (or life-as-a-whole?) viewed as a single-system will be able to reproduce itself. Sounds like the question only makes sense when talking about settling elsewhere than Earth.. Mmm, reminds me of the Fermi Paradox. Will we make it through this!?!
"Anything that, in happening, causes itself to happen again, happens again."
I like how this is not even specific to life nor genes, and it's not hard to add to it the idea of happening-again in ways that make the thing better-or-worse at happening again.
Personally I think this applies to all coherently-causal systems.. still trying to figure out whether to believe QM is fully causal or not! (Currently seems like it might be a mixture?)
I think there are actually still plenty of other dimensions/axes/structures one can think and argue/discuss about even if not many people (or politicians) actually do!
Authoritarianism surely sucks on so many levels though, I will echo that for sure!
The softsynth soundtrack includes lyrics and one of them is "we slow down" which I always interpreted as a kind of demoscener's lament since making things go fast is sorta the whole point!

I am not arguing for either side of the fastness debate, while I certainly adore fast computers I don't like the mental image of our computers all blazing away doing stuff mainly humans care about, while the the world 'outside' is steadily getting hotter and more polluted.
I've played with reaction-diffusion quite a bit, which is an adjacent idea, and there can be some fun in trying to delete all the solitons - which can be an interesting challenge when they behave like like rapidly-replicating gliders!: https://www.mrob.com/pub/comp/xmorphia/F180/F180-k530.html.
My kids enjoyed that as a semi-game like challenge in an RD I made in Android app 'Shader-Editor' on phone, and I reckon something similar but using Neural-CA could be really fun!
Particularly if animated/dynamic (moving) patterns could be developed - like 'The Powder Toy' (et al) but less discrete and more continuous - and far less aliasing!
How about a Terraria-like crafting game, crossed with Powder Toy and using NeuralCA, Reaction-Diffusion and other continuous automata like fluid Sims too! Sounds like it could be fun!?
I doubled the angle so that it doesn't drift to the side any more.. and put it back to 7-symmetry, but left it with the coloring I added (now adjustable via consts):

And a small tweak:

If you squint with it on fullscreen on that last one there's a wonderful mixture of things feeling like they are rotating vs flowing inward-and-outward from 'centers' (like it's ambiguous whether it's curl or divergence somehow for my eyes/brain at least!).
Hooray for sines and cosines and shaders and thanks for motivating me to play!
It struck me as looking a bit like a demoscene plasma effect but with a radial/angular aspect! (also reminds me of cymatics diagrams a bit!)
I experimented with non-integer symmetries and it seemed not to introduce discontinuities, and I made it produce an RGB value for fun too:
The code was really interesting to read and tinker with! I made a version where the symmetry (7 originally) can be other numbers, and that was fascinating to see!
ShaderToy forever!!
I'm on YouTube as 'danwills' and there's the ol' UltraIterator blog below, and a flickr, which is probably the best view for my fractal images at present.

I'm always keen to chat about anything! I would love to turn some of these things into apps or cool games or shaders, so many possibilities! Send me an email:
