From the README

An interactive, high-performance web simulation that models the physical dynamics of an umbrella using a second-order mass-spring-damper system, complete with a reactive 3D rain environment.

Kinematic & Physics Simulation: Implements a robust second-order mass-spring-damper model to simulate the opening and closing tension of a classic umbrella structure. 3D Coordinate Generation: Custom kinematic solver computes realistic spatial transformations for the umbrella's canopy, ribs, top notch, runner, and stretcher links.
