This is a site I found in the great blog "GO2WEB2.0" which helps us internet people celebrate someone´s birthday in a different way. You can write a card where different people can collaborate in different ways: text, images, audio, video. YOu start a card, customize the page and then send an invitation (by e-mail) to other people to collaborate. When the deadline comes, the card is sent to the recipient. I imagine I´d just love to receive a card like the one below.
