         Solve Lagrange's equations for a famous chaotic pendulum (as on
         exhibit at the San Francisco Exploratorium).  Run a movie of the
         result.  By default, the movie runs for 60 seconds, but if you
         supply an argument to the demo3 function, it will run for that
         many seconds.
         The kick= keyword may be used to adjsut the initial amplitude;
         kick= 1.2 is the default.
         You may also wish to supply a damp_time= keyword to see the effect
         of an ad hoc damping term.  damp_time=100 is nice.
