Dimensions from The BBC

"Dimensions is an experimental prototype for the BBC. We want to bring home the human scale of events and places in history. The D-Day landing beaches measured from London to Norfolk in the UK. How far would the Titanic stretch down your street? Dimensions simply juxtaposes the size of historical events with your home and neighbourhood, overlaying important places, events and things on a satellite view of where you live. Certain "Dimensions" can be transformed into short walks, so you can get a physical appreciation of the distances involved"
