i was just looking at pictures posted by a friend who is presently in Angkor Wat and I had a good idea...
i'm sure this already exists since I am not very knowledgeable about technology but, imagine visiting Angkor Wat, or any other archeological site, wearing glasses that have some sort of augmented reality and you could see the site as it once was. like when you'd look at a structure you could see it as it was when it was new, imagined using all we know about the place. wouldn't that be awesome ? !! I've seen so many archeological sites all over the world but its hard to visualize what they were like back then.
