I like the idea of a Lego globe or world!
Having recently been involved in building an OpenStreetMap tileserver I came
across the following project that might be of interest:
Isometric 3D map of Czech Republic
http://osm.kyblsoft.cz/3dmapa/info
...and this page that gives you a zoomable/scrollable isometric map:
http://osm.kyblsoft.cz/3dmapa/?zoom=17&lat=75.75078&lon=14.31372&layers=B
One option would be to change the map style in the osm2pov code and replace the
various buildings and other map items with the equivalent rendered Lego objects.
See my other post about osm2pov on the POV-Ray newsgroup:
http://news.povray.org/povray.general/thread/%3Cop.vrr7em02ufxv4h@xena%3E/
If you fancy building your own tileserver using OpenStreetMap data then someone
has already setup an Amazon cloud instance to do this:
http://tiledrawer.com/
If you want to avoid paying Amazon Cloud service costs then you could always try
building your own tileserver using Ubuntu:
http://weait.com/content/build-your-own-openstreetmap-server
(I'm hoping to try this out at some point)
Bye for now
