Augmented Reality
It would be cool to walk around and be able to watch recorded messages from real people who were there before you and to hear what they had to say.
It would be cool to record yourself in different locations, and then be able to see yourself later on when you returned to those places. You could compare your previous version of your life with the one you are currently experiencing. Maybe people would start thinking ahead more instead of being constantly trapped in the present.
