Call for data

If you have any data you would like to see presented in Google Earth in 4 dimensions (3D plus time), please comment here. The data should have counts of something like:

incidents for incident tracking
sales volumes
polling data
etc.

location data like:

countries, states, zipcodes, lattitudes & longitudes, cities, metropolitan statistical areas, etc.

and the data should also have a time element, if possible, like:

Dates & times of any precision. Could be per century or by the second or whatever.

I am also interested in hearing ideas about what would look interesting or informative in this type of exhibit. Now taking requests.
