Tetrahedral Planetoid, left

Here it is! M.C. Escher's Tetrahedral Planetoid modeled in 3d.

This is the "left" face in the original. Of the two, I like this face better; perhaps it's how the lighting turned out.

This project has taken over three years all told, though there were long stretches of inactivity. 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.
