Fred Murrell sent me this link to a recent presentation at the TED conference. The presenter, Blaise Aguera y Arcas (genius), has developed a remarkable technology (acquired last year by Microsoft) that interconnects geospacial data and imagery, and allows them to be superimposed over one another without concern for the size of the files. In other words, this is really cool stuff.

The TED site was relaunched earlier this year. The interface was designed to incorporate dynamic navigation based on themes. Definitely worth checking out.
