Lee Griggs is a Madrid-based artist who uses 3D animation and rendering software to create these realistic topographical illustrations. Most of them resemble ocean floors, planetary surfaces, or even weather patterns. Each image is made of innumerable colored cubes, cylinders, and spheres extruded to create eye-catching patterns. Lee utilizes Maya Xgen and Arnold to render each image. If you’re ever inerested in creating you own, he shares a couple of tutorials over at his blog.
