Finding Our Way to a Third Life

Talking of geography, here's geograph, which "aims to collect geographically representative photographs and information for every square kilometre of the UK and Eire". That's nice, but I'd like to see this go further.

Imagine if pix were available for a much finer mesh - say, every ten metres (or something). Imagine, then, using some software like Photosynth, a seriously cool piece of software that is sadly closed source (and Microsoft's, to boot), to stitch all those images together into a complete, three-dimensional world - our world - that you could navigate through, while able to see everyone else there doing the same.

Third Life, anyone? (Via Open (finds, minds, conversations)...)
