While reading Tufte I remembered a documentary I saw sometime back on brain research using virtual reality. Posting two links:

It is really interesting how a person was fooled in believing that his body was located somewhere else. How we feel that our "self" is located "behind" the eyes- like a first person shooter mode in a computer game :)
Change the camera position and the brain can be fooled about the location of the body. I would surely like to play a computer game where I am really "in" the game!
