Show HN: Inverse Kinematics in the Browser with Rust

Howdy everyone. I am trying to teach myself some robotics/controls concepts now and I thought what better way than a web application?

This is a demo of an inverse kinematics solver I wrote using gradient descent for optimization. Visualization is done in Three.js, the actual inverse kinematics portion is done in Rust, specifically nalgebra for the matrix operations and ncollide for multiple passes of collision detection.
