Rube Goldberg Physics Simulation

A physics simulation inspired by Rube Goldberg machines: a marble triggers a chain reaction, with ten dominoes each 1.5× larger than the previous one, amplifying the force from desk scale to room scale, ultimately toppling a 1.8-meter domino. Built with Three.js and Rapier physics engine. Perfect for physics education, satisfying chain-reaction videos, or creative coding shorts. <<<DESCRIPTION>>>
