From 2D to 3D: Escher Drawings - Crystallography, Crystal Chemistry, and Crystal "Defects" part of Cutting Edge:Mineralogy:Activities
This set of exercises illustrates plane and space groups as well as crystal chemistry and "defects" in crystals. The problems are designed to present the material as puzzles that are visually attractive and intellectually challenging.

From 2D to 3D: II. TEM and AFM Images part of Cutting Edge:Mineralogy:Activities
High-resolution transmission electron microscopy (HRTEM) provides 2-D projections of mineral structures at almost the atomic scale, and atomic force microscopy (AFM) provides 3-D information about the surfaces of minerals. By using these instruments, we can learn about defects in minerals and their complexities. The mineral examples in this problem set include representatives from several silicate structure type, sulfides, a sulfosalt, and a carbonate.
