This artwork was made using complex procedural deformations and a completely procedural shader. Made entirely in Blender 2.76b and rendered in the powerful Cycles render engine.
The mesh is deformed using procedural methods, however a mesh this complex required a lot of data, so there is a total of 5,000,000 vertices (yes, that is five million). Using the revolutionary pointiness feature in Cycles, I was able to apply a different "cold" material to the outer parts of the mesh, and a "hot" melted inner core.
