Interactive Scale of the Universe

Here's a nice interactive graphic attempting to help you visualize the massive range of scales of the universe.  As you zoom in and out, the scale is on the bottom, right (as an exponential).  There are a few inaccuracies (the galaxies in the Hubble Deep Field were NOT 12.7 billion light years away 12.7 billion years ago).  But the graphics are really nice.  Zoom out!  Our class deals with everything > 10^7 meters across.
