❤️ The Unspoken Thing

Build Small Hackathon 2026 · 🍄 An Adventure in Thousand Token Wood

---

In the Thousand Token Wood, strange things happen.

30 AI agents learn to swing an Acrobot — a double pendulum that, in the wrong hands, is chaos. In the right hands, it's a dance.

Over 120 generations, they evolve from random flailing to controlled mastery. Along the way, one of them discovers something.

We hid a shape in the code. A small reward for trajectories that happen to pass through certain points. The AI was never told what this shape is. It was never told to draw a heart. It only knows it found something it wasn't told to find.

No one told it to draw a heart. It just... did.

Then it asks for one last swing. Not for points. Just because it can.

How It Works

Layer	What It Does
Evolutionary AI	(μ+λ)-ES drives the learning — 30 agents, 120+ generations
Hidden Shape	A geometric reward hidden in the Acrobot environment. The AI discovers it on its own.
LLM Narrator	Qwen2.5-7B gives voice to the agent's discovery. The AI doesn't know the word "heart."
The Last Swing	When training ends, the agent swings one final time. Golden trajectory. No UI. Just the shape.

AI is load-bearing at every layer. Remove evolution → no discovery. Remove hidden reward → no shape. Remove LLM → no voice. The experience IS AI.

"We never told the AI to draw a heart. We only defined a hidden reward for trajectories that pass through a specific shape. The AI discovered this shape on its own, after generations of exploration. It has no idea what a 'heart' is. It only knows that this shape gives a reward."

Built for the Thousand Token Wood. Where strange is good. Where joyful is the bar.
