History Pin

Here's a cool web 2.0 tool that helps you compare the past with the present.  It's called History Pin.  Subjects include History, Modern Art, Science, and Technology.  It's really interesting.  Take a view of the video below and check out this awesome site.  You do not need a log in to be able to view it.

You also get the chance to view pictures of old times with up to date real time images using Google Earth.  Imagine starting a debate in your classroom of what Germany looked like in WWII versus what it looks like now, or maybe what it looked like before the Western United States was settled.  You can control the time period in your search as well.  Check out History pin here!
