Every tile runs in your browser. The bulk are the Project Genesis series — real cosmology, neuroscience and econometrics through the one engine, honestly framed.
The HRL Lab — live
The generic engine running in your browser: DNA complement by relaxation, order-3 molecular chirality (R/S), and few-shot label propagation.
newest ✦HRLized — music by relaxation
The engine composes: pitches are labels, melodic smoothness & chord tones the constraints. It relaxes a melody and plays it. A tiny answer to Suno.

topologyNew with Elbie · Gooblets & ZappiesFour fresh features in the little world
The Gooblets & Zappies world keeps growing — designed hand-in-hand with Elbie. The four newest additions, each a small rule layered onto the same relaxation-labeled world:
🪻 Blue Flowers
A peaceful Nature Gooblet crosses the Grove portal up to the surface under a 🤝 Helpful King and plants up to three blue flowers as it roams — a new entry in the Plantiary.
new🐉 Grown-up Dragonlings
Once a Dragonling grows old enough it grows up — bigger, winged — and stops hunting to fly home to the Dragon Island and rule alongside the Dragon King.
new👑 A Fireproof Red King
The hero who slays the Fire Giant and rises as the Red King now walks through lava and fire completely unharmed — the flames can never touch him again.
new👑 The Monarch Tracker
A new tool opens a live panel naming who wears each of the five crowns — Sea, Dragon, Human, Fire and Nature — or — none — when a throne sits empty.
newThe EngineOne core, many compatibilities
Relaxation labeling (Rosenfeld–Hummel–Zucker, extended with a learned noise label) takes a set of objects, a set of labels, and a compatibility function that says how much one labeled pair reinforces another. It iteratively relaxes the field into a mutually consistent labeling. Only the compatibility kernel and prior change between domains:
| Domain | objects | labels | what compatibility encodes |
|---|---|---|---|
| Cosmology | galaxies / parcels | void · filament · cluster | local density & neighborhood coherence |
| Neuroscience | neurons | sensory · inter · motor | directed synaptic flow through the connectome |
| Econometrics | forecast origins | candidate models | recent accuracy + temporal coherence |
| Motion capture | measured 3-D points | skeleton markers | inter-point distances match the model |
| Strategy | chess pieces | tactical roles | roles that co-occur in a real plan |
The Python core is a tested library (hrl.core.RelaxationLabeler) — see the
repository.
