The software ReciPro makes various crystallographic calculations, visualizes a crystal structure, simulates a diffraction pattern and high-resolution TEM image, indexes diffraction spots, plots stereographic projection, and so on.

Library for processing of chemistry related files (aiming at spectroscopy and structural files)

Parse the CIF file format for Protein Data Bank (PDB) data.

Generates bitmaps that approximate a quazicrystal lattice structure with n-rotational "forbidden" symmetries, or in other words: it makes really pretty pictures.
