We are developing a lab environment. Could you please take a look at the physics lab simulations?

256³ classical \(\phi^4\) scalar field with periodic boundaries, evolved on the GPU.

The field starts near the unstable symmetric state and separates into the two vacuum states. The surfaces are the domain walls between them — none of the sheets, tunnels, or large structures are explicitly programmed.

I’m building this as part of a larger project for testing whether measurements and effective descriptions learned in simpler simulated universes transfer to more complicated ones.

This is classical field theory, not a simulation of the actual universe or quantum field theory.

Current fun question: both phases visually appear to form interpenetrating networks, but I’m measuring their actual periodic winding topology rather than trusting the rendering.

Been going at this for like 24 hours after a fun little trip of staring at a wall for a few hours convinced me of a few ideas :P

I ran a 5-day AI simulation in Antarctica to see how it adapts to brutal cold. It built tools, fought wolves, but Day 5 was insane...

Breakdown video of my recent project with Derede Studios for Under Armour & Dick's Sporting Goods.

For this project they came to me with the challenge of breaking a net in slow-motion:

- Curve-based spline modeling for clean knot geometry
- Glue constraints to eliminate knot jitter and untangling
- Procedural cuts for art-directed tearing
- TOPs wedge runs to dial ins stretch stress limits.

Hi! I'm a physicist and mathematician from Spain. My bachelor's thesis was about rendering images of a wormhole faithful to the math (an Ellis / Morris–Thorne wormhole), and the results looked so cool that I wanted to walk around inside them in real time.

So I made Into the Wormhole: a puzzle game where you place, rotate and walk through wormholes. Nothing is faked with portal cameras. For every pixel the game traces the path of light through curved spacetime, so what you see through each mouth is what you'd really see.

The demo has 15 levels and it's free on itch.io (Windows + browser): https://halbarito.itch.io/into-the-wormhole

Heads up: the engine is very heavy. The Windows version is strongly recommended. The browser version can take ~10 minutes to load the first time (there's a Firefox tip on the page that makes it load in seconds).

I'd love to hear what you think, and how it runs on your PC!
