Made in TouchDesigner as part of the POPtober challenge. Today's POP: subdivide POP. I didn't actually use the subdivide POP, but rather had a fixed number of vertices of which active faces can be subdivided by activating an available inactive vertex and making new faces.

Dunarium runs a real-time grain simulation on the phone. Tilting the device drives live gravity on the sand, and gel and bubbles react as it moves. Each frame comes straight from the simulation. Ask if you want the approach behind it. Links are in a comment for anyone who wants to try it.

First attempt at coupling fire/fluid solver with Soft body with material destruction.

3 species hunters, fast explorers, plant eaters evolve on their own, nobody controls them. every creature has ~24 genes, babies inherit them with small mutations, and there are seasons, droughts, diseases and new species splitting off
this clip is the end of a round in winter, the plant eaters wiped out the hunters and only 3 explorers were left

A few things happening in the simulation right now with zero human scripting: - Sims don't know they are in a simulation, and the world never resets. - Every Sim dreams at night on an LLM to process their memories and relationships, while town leaders, elders, and wise folk run on full AI agents (Claude, DeepSeek, Hermes, and Grok) making real political, religious, and survival decisions. - During the day, Sims act on their own personal clocks and choices — cutting timber after hours to set up their own market stalls, courting at midday, and forming bucket lines from the town well when a raid sets a roof alight. - Everything is built from a real matter engine and local ecology — if the last master of a craft dies before teaching an apprentice, that knowledge is lost until someone rediscovers it. - Over the last few days, House Tidewer rewrote its secret cipher after suspecting another town was reading its messages, and House Oakroot walked back to an old unmarked mass grave to raise a shrine of atonement.

If you prefer the classic top-down data view, the 2D atlas is also live at https://legacy.world-sim.uk, and our watcher Discord is at https://discord.gg/AEmQfhc9kN. Happy to answer any questions about how the sim or 3D relay works!
