+# Physics Generalization Dataset
+
+**1,000,020 diverse 2D rigid body physics simulation scenes** for training and evaluating LLMs on physics prediction tasks.
+
+## Overview
+
+This dataset contains procedurally generated physics simulations across **30 distinct scenario types** organized in 6 categories. Unlike typical physics datasets that only feature random objects falling in a box, this dataset covers a wide range of physical phenomena: collisions, stacking, ramps, pendulums, constraints, and mini-game-inspired physics.
+
+Each scene is a 200-frame simulation at 1/60s timestep using the Pymunk (Chipmunk2D) physics engine, exported in JSONL format with rich metadata.
+
+## Dataset Structure
+
+### Splits
+
+| Split | Scenes | Scenario Types | Purpose |
+|-------|--------|----------------|---------|
+| **train** | 900,000 | 24 (seen only) | Training |
+| **val** | 100,020 | 30 (seen + unseen) | Evaluation |
+
+### Unseen Scenarios (held out from training)
+
+6 scenario types appear **only in val**, enabling out-of-distribution generalization evaluation:
+
+| Difficulty | Scenario | Description |
+|-----------|----------|-------------|
+| Simple | `pong` | Ball bouncing between two paddles (zero gravity) |
+| Simple | `bowling` | Heavy ball rolling toward arranged pins |
+| Simple | `ramp_roll` | Objects rolling down an inclined plane |
+| Complex | `angry_birds` | Projectile launched at multi-layer block structure |
+| Complex | `hourglass` | Objects falling through narrow gap between chambers |
+| Complex | `newtons_cradle` | Balls suspended by pin joints, momentum transfer |
+
+### Seen Scenarios (in both train and val)
+
+24 scenario types with 37,500 samples each in train:
+
+**Collision & Ballistics:** `billiards`, `breakout`, `explosion`, `head_on`, `projectile`
+
+**Stacking & Structural:** `bridge`, `dominos`, `jenga`, `pyramid`, `tower`
+
+**Ramps & Terrain:** `funnel`, `marble_run`, `plinko`, `ski_jump` (+ unseen `ramp_roll`)
+
+**Pendulums & Constraints:** `chain`, `pendulum`, `seesaw`, `wrecking_ball` (+ unseen `newtons_cradle`)
+
+**Mini-game Physics:** `basketball`, `pinball` (+ unseen `angry_birds`, `bowling`, `pong`)
+
+**Complex & Chaotic:** `avalanche`, `conveyor`, `orbit`, `wind` (+ unseen `hourglass`)
+
+## Data Format
+
+Each scene is a JSONL file (1 header line + 200 frame lines).

+  ]
+}
+```
+
+## Key Features
+
+- **30 scenario types** with qualitatively different physics (not just parameter variation)
+- **Difficulty scaling** (1-5) per scenario: controls object count, velocity, structural complexity
+- **Deterministic** generation via seed-based RNG
+- **Constraints/Joints**: PinJoint, PivotJoint for pendulums, seesaws, chains, Newton's cradle
+- **Custom static geometry**: ramps, funnels, peg grids, bumpers, hourglass chambers, basketball hoops
+- **Rich text descriptions** for each scene (useful as LLM context)
+- **Zero gravity** scenarios: billiards, pong, orbit
+- **Initial velocities**: projectiles, explosions, head-on collisions (not just "objects at rest")
+- **Clean train/unseen split** for generalization evaluation
+
+## Physics Engine
+
+- **Pymunk** (Python wrapper for Chipmunk2D)
+- Scene: 800×600 pixels
+- Fixed timestep: 1/60s
+- Elasticity always < 1.0 (energy conservation, no Pymunk instability)
+- Threading disabled (determinism)
+
+## Generation
+
+Generated using 22 CPU cores in ~29 minutes at ~578 scenes/sec.
+
+```bash
+python scripts/generate_scenarios_dataset.py --split all --workers 22
