At my mother's 70th birthday party yesterday, we created a "memory book" by taking photographs of the guests with a Polaroid camera. The reaction of my six-year-old daughter, who was annointed the "official" photographer, about how a Polaroid camera worked was priceless. She was totally blown away by the idea  you could take a photograph and see it develop before your eyes in about 60 seconds. In an age of digital this and digital that, it was pretty eye-opening to see someone so impressed by such an "antique".
