Trulia Hindsight

Trulia.com has a Hindsight feature that is very cool. It shows development patterns on maps like timelapse photos. While I already had a good sense for the patterns in centralized cities like Madison, WI I was still a little startled to see the pattern between Nashville and Smyrna. And a place as remote as Aspen is fascinating to watch.

Point of information: Trulia.com is a real estate information website. But it is hard to see how that might be impacting this application.
