Particle Lenia is an Artificial Lifeform that consists of point particles that produce potential energy fields, and try to minimize their local energy. It's inspired by Lenia ( • Lenia - Mathematical L... ) and FlowLenia (arxiv.org/abs/2212.07906).
The sound mapping is genius
Oh, that's what it was 😂
Wow, what a treat! Awesome things about this paper:
- Finally, we can see actual 3D Lenia! (not just 2D Lenia with colors)
- You gave really cool sounds to the particles based on their potential energy and speed.
Both of these things are possible because you used particles to represent matter instead of a scalar field. Also, your paper is really accessible: You released it in an interactive format and your explanations are clear and easy to follow.
Congrats!
Thank you!
The visuals and sound are both incredible, and I’m excited to see Lenia continue to be modified!
I hope to someday see a system like this where the patterns are capable of evolution via reproduction/mutation.
But for now, this is pretty dang cool.
So living organisms danced into existence from the music? I see
@@agoogleuser2507 Well, according to Tolkien’s legendarium mythology, yes!
Didn't you watch a video? They do exactly what you written - evolve, reproduct, mutate. That was the whole poin of video.
@@user-ut4vl8bw2k I guess we have different definitions of those words
@@user-ut4vl8bw2k They're obviously talking about a more sophisticated simulation, one where organisms need energy to continue living. This is cool, but it doesn't feel as real as a simulation that would use simple rules as well as an energy system to watch organism grow, eat, metabolize, reproduce, and die.
amazing sound design
I’d love to understand how it works.
I’m a board game making natural philosopher and designer. This is the motivation I need to learn some coding. To me this kind of system is like the music of Bach, organic and rule produced at the same time. Thank you for showing us your work!
Gödel, Escher, Bach
this is insane, i was thinking how even cooler lenia would be with particles, and here it is
fantastic work here.
especially appreciate this as a intuitive solution for conversation of mass, and for giving us a microphone into the system!
agreed on the sound, the combination really elevates this fascinating work.
I love this, going kinda full cycle, starting with Game of Life, abstracting the rules into continuous transformations, and then rediscretizing them into a particle version.
I wonder how far off it is to turn this into a full on life simulation. What would need to be modified about this concept to introduce stuff like food and environmental factors and such...
It's the most life-like thing that isn't really going for free form selective pressure I know of right now.
I think the main tricky things here are:
- How do you delineate what an organism actually is? In Lenia that's an entirely emergent phenomenon, right? And actually it'd be cool if that emergence could be preserved. Imagine something that starts from "primordial soup" and manages to go arbitrarily complex from there! Ideally you wouldn't predefine where an organism starts and ends. It'd just be whatever the current configuration of particles ends up doing.
- How do you ensure preservation laws (of energy, momentum, angular momentum, matter)
- How do you introduce a "cost of living" (where the emergent organisms can't move or replicate without adequately eating and such)
Those are things I think aren't really considerations in GoL or Lenia. But it'd be really cool if all that were possible to include.
I think it will become something like "Matrix" in the future
I saw a game like that, it was about going from single to multicellular.
@@TheRepublicOfDixionconderoga another piece of the puzzle actually happened recently - check out "flow Lenia" if you have the time
Real life is not well-understood, but it is at least partially understood to the atomic level, both physically and chemically. A simulation where actual evolution occurs needs both physics and chemistry to have such dynamic behaviors, and an insane amount of particles and energy.
You start with that primordial soup. Most of it becomes mundane clusters of matter and energy, like stars. Small pockets of matter, like planets, may by random chance have the exact conditions for evolution to take place.
Gravity and relativity are important because you can’t simulate all of it at once; you subdivide the entire universe into “large” (yet such small) chunks so that the simulation of the universe is in fact only some form of a cellular automaton. Information cannot travel faster than the speed of light. Or, in terms of the CA, information is sent from one cell (chunk) to another, in a continuous, nonlinear way.
@@JordanMetroidManiac Lenia sort of simulates chemistry already. In a rudimentary way with not all relevant constraints presents, but effectively, it's quite similar to chemical reactions.
There was an attempt to get a reaction diffusion version of Lenia (which is something you could achieve with real chemistry in a petridish) and it got pretty far. After a few modifications to the original version of Lenia into what's called *Asymptotic Lenia,* the issue ultimately turned out to be a nonphysical breaking of the mass equations.
However, there is also another recent independent modification of Lenia called *Flow Lenia* which kind of solves the mass issue. I'm not sure whether that's enough to resolve the issues with the reaction diffusion attempt, but if it is, that ought to make it possible to, at least in principle, allow you to "run" Lenia in a literal real life petri dish given the right reaction chains. (It might be highly nontrivial to actually find suitable reagents though)
As for the laws of physics, other than gravity, chemistry mostly already captures all physics you need for life. And if you are doing a 2D petridish style simulation you can basically neglect gravity.
If you actually want a 3D sim that also involves gravity, that should be perfectly possible by simply adding an external force that always pulls stuff down.
A full simulation would probably also amount to simulating Navier Stokes though, which is certainly gonna be much trickier.
The sounds and graphics are what's best about this interactive software. The "spinners" I think are pretty interesting, and I think they are just very slow oscillators.
Thank you for making this video so simple. I'm tired of videos that go in depth about the math/code of these programs. I just want to see cool patterns; I couldn't care less about how it works.
i would LOVE to see this polished and released as a "game"
This looks exactly like something I'd find under a microscope! +1!!!!
Interesting, I gave the online simulator a try and made a neat self propulsion group of particles. I do find it interesting that there is a resistance to hexagonal crystal like structures without collapse occurring.
That exactly what I was going to ask for do you have a link
Water also has a resistance to form a flat hex lattice like graphene. It's a 3 atom tetrahedron and can go antigravity in a nanutube bundle. Where's Leonard Suskind, dHooFT???.. can the sim work on a lattice sphere.. make a space time swimmer group that might use the curvurature suspected to be compactified
@@DamianHallbauer videos description has it
This is simply amazing and beautiful! Will be digging into the code and see what we can find. Thank you for sharing this!
The sounds make me want to make an automated musical instrument out of these
Are the sound effects added manually on post or are they generated along, from the simulation data? :) The latter would be awesome.
its not added manually. I'm sorry i can't give any explanation tough :)
Every particle emits a waveform with a frequency depending on its interaction "energy". Here is the code where I prototyped that effect colab.research.google.com/github/google-research/self-organising-systems/blob/master/notebooks/particle_lenia.ipynb#scrollTo=L9SckwekgO3U
How they get energy to move? I not seen any new particles coming and they also not looze particles. For me it looks like you programmed perpetual engines in 2d space with some special unreal physics. Did you try to emulate energy loss on movement?
This feels like one of those experimental VST instruments
Question is the particle size related to its charge
Amazing, thanks for sharing!
Probably the only thing I would say is bad about it, is that most browsers have holding a tap as a different function, preventing interaction on mobile.
This is SCARILY genius.
Amazing, great work
amazing work!
This is AWESOME!

Best quality: Its wiggles
Im really curious about how the sound us generated
Yet to look at the implementation, but i wonder "Inspired by Lenia"...But, does it have anything in common, from a technical point of view? I've seen some impressive Particle Life clones lately, and it seems more related to those than Lenia's CA approach?
In the article we discuss parallels with (Flow)-Lenia in detail google-research.github.io/self-organising-systems/particle-lenia/
Make this a neural or cell instrument game, and the way they set it up will determine the song or resonance that the individual then the whole will have.
Seria onteressante colocar regras basicas de física 2d aplicadas a um virus simples, colocar as propriedades de cada conjunto do genoma deste virus e sua função, e ver como a lenia se comportaria nestas regras.
Is there any practical use of such system, or is it made purely out of theoretical interest? Don't get me wrong, it is interesting and I made something similar in the past, but it seems that many other people are interested in lenia systems, and I don't understand why this particular set of systems draws so much attention
also just stright up giygas i love this :P
Wow thank you
Please explain how this works! Its amazing i dont think i've seen anything like it?
They honestly remind me of protocells
WOOOOOOOOOOOOOOOOOOOO
How was sounds made?
I wonder about that too
Is there an explanation of the physical laws of this simulation?
google-research.github.io/self-organising-systems/particle-lenia/
Why is this in my recommended yet it looks cool?
Nice. But I don't understand what is it about? It is real particle? What kind and how do you video them? If you add some explanation that would be very useful. Thanks

WOW👍
This conways game of life remastered
Am i right or not pls tell me
wrong

3:13 trypophobia kicking in
Well… now is circle
hello my friend, I love you
Is it the geometry of GOD? Where did the first code come from? Very interesting - Kepler and plato would freak out!
cellular organisim
speen
Can someone tell me the rules of these
Edit: i just found out the whole tim- HOLY SHT IM 2ND IN COMMENTS
There’s a problem!!!!
cosmic horror
It sounds a bit creepy to be honest
