Thanks to Bob Hanson, Jmol as used by ICSD web servers, can now display
anistropic temperature ellipsoids while rotating the structure in real
time. See http://icsd.ill.fr/icsd/help/CIF-help.html and click on the
simple KCaF3 example then click "Demo" on the login screen.

Choose "Ellipsoid solid" for the traditional "jelly-bean" ellipsoid
drawing, and rotate the structure while holding down the mouse button.

You can draw your own structures using this WWW interface, including
anisotropic temperature ellipsoids if the Uij matrix is given in your CIF.
For an example CIF, click the Jmol logo in the display and select
"collection..." then "kcaf3.cif".

Thanks to Brian McMahon, Jmol structure display is also available on-line
for papers published in IUCr journals. See: http://journals.iucr.org/
select the structure and click "3d view".
