ILL's most popular WWW page, our 3D-crystals gallery of VRML models, has been completely re-written. The subjects now covered include how atoms pack together, the structure of simple compounds, minerals and gemstones, structural transitions, ferro-electrics, fullerenes and nano-tubes, molecular sieves, superconductors, giant magneto-resistive and other new materials. Each structure is illustrated with high quality GIF images and 3D VRML models. The complete package can be downloaded for off-line browsing from the index page: http://www.ill.fr/dif/3D-crystals/ (A prize for the person who finds the first error :-) Merry Christmas !
