Anders just told me to look at this great video about the Open Street Map project.
It’s very impressive!
It’s showing the development of the OSM project on a rotating globe within the last year.
Here’s short out-take:
An animation showing edits to the OpenStreetMap.org project during 2008. OpenStreetMap is a wiki-style map of the world and this animation displays a white flash each time a way is entered or updated. Some edits are a result of a physical local survey by a contributor with a GPS unit and taking notes, other edits are done remotely using aerial photography or out-of-copyright maps, and some are bulk imports of official data.
