Devin Coldewey has a great write-up on some new things the Surface team rolled out including their new SDK. But, more relevantly, a photo geotagging application for Surface using Virtual Earth. Per Coldewey, “Next we saw probably one of the coolest things I’ve seen in a while. Essentially a geotagged photos viewing application, it had Virtual Earth (very fun to play with, as I did without permission for a bit) and spread across the world were little photos. The photos were placed on the map exactly where they were taken and they could be selected by hand gestures, or filtered by other means so that only, say, panoramic photos taken in 2007 would show up.“
That IS pretty cool!
