hugh3, you are exactly right. I updated the original post as I was thinking through how this amazing physics experiment could be helpful, and it dawned on me, it wasn't. I could just use my Canon to accomplish the same thing. I think my brain was more caught up in the fun of walking through the thought than accomplishing something with it.

  Even so, I think it would be fascinating to interact with a device that consisted of mirrors, even if was just to experience a delay of a millisecond (or whatever is the minimum amount of time to perceive a delay).

    You can slow down light http://news.bbc.co.uk/2/hi/science/nature/655518.stm http://news.bbc.co.uk/2/hi/science/nature/655518.stm and see the past!

      Exactly. I think it'd be incredibly cool to walk in front of a thin transparent wall with this property, run around to the other side and see yourself walk along it. I wonder if you could information in this fashion.

Not if you consider the resolution would be much higher then anything technically feasible. You might not now what you want to focus on before hand, but if the system is setup you can go back and decide what to look at.

I think this would have other uses. Presumably, this thing would not use energy; it would just pass photons from A to B. Make one a meter square with a twelve hour delay and point it to he sky, and you have instant lighting at night. It would he like a battery storing solar energy coupled with a lamp. Unfortunately, even if we could fold a 12 hour light path into a tiny space, losses would probably be too high. Some of the light that got in would come out after 12 hours,but most of it would be converted into heat long before.
