How Big is it?

In my ceaseless quest to bring you the best of the web (you do remember my post on the Transiberian Express?), I would like to recommend a site called BBC Dimensions:
http://www.howbigreally.com/

The BBC has launched a new site where you can visualise the scale of important historical places and events by overlaying them on a map of a location that you are already familiar with.

For instance, you can set your city as the starting point for the Great Wall of China to understand how massive it is. Or if you wish to know how far the astronauts walked when they first landed on the moon, simply overlay that area to some familiar neighbourhood.

There’s a map of the Tora Bora caves in Afghanistan where Bin Laden was thought to be hiding. Once you see that area relative to your own location, you suddenly realise how big it is.

I think it's very interesting!
