motor babble

a browser physics game about the hardest reinforcement learning problem anyone ever solves: being a baby. every letter on your keyboard fires a muscle in a floppy newborn ragdoll, the wiring is hidden, and it gets re-scrambled every run. figure out your own body by mashing keys, roll over, survive tummy time, and crawl across the nursery to your parent.

a companion python package ships a full gymnasium environment of the same baby (pymunk physics, same 8 muscles, same milestones) with ppo training via stable-baselines3. can your policy learn a body it has never met?

the nursery is loading. if it never appears, you need javascript and a physical keyboard.
