Mini Lego StreetView Car - This 8-Bit Life
I just saw a nifty little project on Hack a Day where a hobbyist built his own StreetView style car out of Lego NXT parts. The car works as you might expect, traversing streets and taking images, tagging them with gps coordinates as it does so. This is a pretty interesting project, I hope we see more progress on it.
