Tetrahedral Planetoid

These are some sequential images from my project to make a 3d model based directly from the picture "Tetrahedral Planetoid" by M.C. Escher. It's coming slowly, but I hope you enjoy the results as much as I have.

The process of creating the geometry has been much more grueling than I anticipated. Getting all of the odd faces to match up, while maintaining the beautiful regularity of the model has proven extremely challenging. Even thinking about modeling some of the shapes has taken a while, and I have yet to develop a consistent mode of thought which can adequately address all of the issues I've encountered. I encourage anyone wishing to stretch their spacial perception and 3d modeling skills to tackle this simple yet elusive object.
