These chains are created using GLSL code, using a method of 3D rendering called raymarching. Raymarching uses contained mathematical functions to describe shapes and the materials. Raymarching is physically based in that it follows rays of light around the 3D scene somewhat similar to how photons move in the real world. This allows materials like iridescent metal to bend and twist as if they were created of goo, creating a dissonance between the material and it's physicality. The music is by dance and electronic music duo slowdanger.
