This is one of the most fascinating forwards I've ever received. I kept going back and forth on each picture and was totally mesmerized. This is an incredible use of technology, like traveling back in time. Just click on the photo anywhere and it will become 2014. Click again and it will go back to 1944; or you can left click and hold on each photo, and then drag your mouse across the original photograph and it will be become a photo of the exact same location and view in 2014. Drag it back and you are in 1944 again. Click then scroll down for more pictures. http://interactive.guim.co.uk/embed/2014/apr/image-opacity-slider-master/index.html?ww2-dday
Here is a site with some very similar photographs of Pearl Harbor, both 1941 and in 2013. But they did it a different way, actually superimposing one photograph on top of another. https://www.navy.mil/ah_online/ftrStory.asp?issue=3&id=78115
