Free software

A selection of DOS and Java computer programs covering various crystallographic aspects may be downloaded from my website (http://www.nirim.go.jp/~weber): structure display; diffraction pattern simulations (Laue, precession, powder, Kossel); stereographic projections; 3D reciprocal space visualization; point groups; wallpaper patterns; quasiperiodic tessellations; polyhedra and crystal shapes; vector visualization; periodic tables; Fourier transforms (FT); difference plot.

Editor’s Note: Steffen asks you to make a contribution to UNICEF if you like his programs and continue to use them.
