I have been interested for a while in the idea of the 'corporate mashup'. What could be done with corporate data mashed up with things like Google Maps and other visualizations? I found this one today from the World Bank -- summaries of its projects in a Google Maps mashup.

It is also very good to see that these organizations are starting to open up access to this information -- triggered in no small part by Hans Roslings at Gapminder.
