[Users] Demographic change interactive map examples?

[Robert Buckley]

Hi,

does any have/or does anyone know of any interactive maps which were developed 
with Geoext using opengeoserver/-suite?

This field will soon be landing on my desk and I would be interested in any 
examples which show demographic change over a period of years with emphasis on 
interactivity. Has anyone seen a sliding tool to change the contents of a map? I 
am imagining a sort of year slider with which one could change the population 
statistics for a region.

Thanks for any suggestions,

Robert Buckley
