Heat Map + Papervision3D

Doug McCune (one of my all time Flex heroes) contributed heavily to SpatialKey, which looks and works great. Got to see it last week at 360|Flex in San Jose. I've been wanting to do something similar, but in 3D! Dabbled a bit with Papervision3D, but wanted to get into it, and that was the perfect opportunity. The idea that I had was to read a country shapefile, and thematically map all the cities in that country based on some attribute. And do all that on the client using Flex. I did a little bit of research, and here is a list of sites that "inspired" me:

And here is a snapshot of the result:


You can download the source code of the application from here. And you can see a sample demo here.
