time series representations in Mapserver

[Fawcett, David]

I seem to remember an app, possibly by DM Solutions, to track West Nile Virus in Canada.  It was a few years ago, and I believe that it used animated .gif's.

OK... that's a start.  However, I'm looking at weather observations, 
usually they're from fixed sites (well, excluding the storm chasers:-). 
  I'm wondering if anything's been done for animation-ish stuff, so I 
could display the temperature contours, or, for instance, a changing 
landscape of wind barbs...

Thanks, Gerry
