 We were keen on MPEG around 1992, but abandoned it
 largely in favour of hyperactive molecules;
 http://www.ch.ic.ac.uk/chemime/
 where the user can experiment with the data, rather than having
 a predetermined view imposed upon them.
 Might  I highlite the work of a colleague, Arie Aizman, and
 his work on symmetry which exemplifies perfectly why we
 abandoned MPEG in favour of richer formats;
 http://www.ch.ic.ac.uk/vchemlab/symmetry/
 and in particular the molecular vibrations section.
 For more complex surfaces (ie  MOs, ESPs etc etc),
 one would use  VRML instead of MPEG.
 Perhaps the simplest concept which explains why MPEG
 is not promoted is that it cannot be easily indexed!  Molfiles,
 PDB files, VRML files etc are all more easily indexed than
 MPEG.
