1. Concept Overview: More Than a Game Mr doob Ball Pool (often found on mrdoob.com ) is not a game in the traditional sense — no scores, no levels, no win condition. It is an interactive physics sandbox built in Three.js by the legendary web pioneer Ricardo Cabello (Mr doob) .

At its core: a shallow 3D box filled with colorful, shiny balls. You click, you drag, you fling. The balls react with realistic momentum, friction, and collision. That’s it.
