Fun? Perhaps... but better described as informative and about as accurate as you can get as far as the historical aspects of it. It's appreciated to see this information being given out to strip away the sometimes ridiculous mythology of the art.
One of my friends (whom I've mentioned here before) tries to tell me about how he's able to disappear and all that ... I challenge him by leaving him in a room with one door and a small window... voilia there he is hiding either under the bed or in the closet behind some boxes... sheesh. C'mon now please.
