Another new, cool visualization tool - Trulia hindsight

Wow.. another new launch today from Where.. this time its popular real estate resource Trulia who've added truliahindsight - an amazing new way to visualize change and trends via a clever mapping UI with animations. The site is the result of a collaboration between Stamen Design (stamen.com) and Trulia. The animations you'll access use the year the properties were built to show the growth of streets, neighborhoods and cities over time... interesting as you browse changes in San Fran and you'll see how with a rise in price people tend to migrate to the hills and closer to the coast (as can be expected). What a great visualization tool and a fun experience for the user - check it out at http://hindsight.trulia.com/
