Sorry if this has already been posted, but I just saw this and it's really rad. Esquire Magazine's 75th anniversary issue has a screen with moving words and images on the cover. It's a technology called electronic ink. Think of what print media will be like when this technology gets really cheap. (Or how it might revolutionize certain magazine industries...)
Read about it here and check it out if you're near a bookstore or newsstand.
