Molecular Dynamics film for teaching.

 Hi.
 I am giving a short introductory course on molecular dynamics of
 proteins and nucleic acids.  I am looking for an appropriate film that
 could be used as a teaching aid and that demonstrates the utility of such
 calculations.  Any information regarding such a film and how I might be
 able to obtain it would be very much appreciated.
 Sincerely,
 Lindsay Eltis
