2 minutes with a book

ever tried to get as much as you could from a book in only two minutes?
This is what we did in class yesterday and it created a very interesting take on how I look at books. All the books were very different and were meant to have some connection to a means of documenting somewhere, someone, something. With some of the books I found myself so fascinated I didn't want to give it up after two minutes had passed and with others I didn't have time to become very intrigued. The content and imagery also brought out a range of reactions in me.
I think it would be fun to try this in a bookstore. Allow a certain amount of time, 30 minutes, an hour? and spend 2 minutes with every book you pick up- no more and no less. Try it.
