Watch a tiny brain learn to fly.
How it's built
- PPO, GAE and backprop from scratch, gradient-checked
- Trains in a Web Worker, identical brain in Node and browser
- Petals, imagined path and value contours drawn live
- World editor, fly-it-yourself baseline, share links
- Aviary and daily board scored by a server re-flight
A newborn neural network teaches itself to land a paper glider on a perch, live in your browser. PPO is written from scratch; the chart draws what the brain predicts: action petals, its imagined path, and its value field as contour rings. Change the world, fly it yourself, share trained brains, publish to an aviary and take a daily course the server scores by re-flying your brain.
