I've photoread many books upside down and backwards. The idea didn't seem that odd to me because I was already able to regular read a book upside down.

I've even done it in libraries and bookstores to see how others might react. It's soooo easy to Photoread in libraries and bookstores. Everyone is soo busy in their own little worlds that they don't even see something that might break the paradigm for them. I've even sat on the floor in the local library mind mapping a book I just Photoread. People around me acted like it was an everyday occurance.
