In my opinion Memories are the ones responsible to remind you of, who you truly are and where you come from. I could not see myself living without memories and always remembering past experiences, that really teach you how to grow as an individual.
Here's another transparent building. The magic in this picture is that the building and photo are both real, but the photo somehow give you the impression that you are seeing transparent skeleton of the building only. The windows are placed in such way to give you reflection of the opposite side of the building, thus making it look so real. I love this optical illusion, Don't you?
