I just found a link to cool article on Digital Arts online, about some 3D book covers that have been made by Vintage Books, for some classic horror and science-fiction novels such as 'Planet of the Apes', 'Journey to the Centre of the Earth, and 'The Lost World'. They work by the viewer wearing some of the classic red/blue 3D glasses, and the covers then jump out at the viewer, adding a more interactive experience to buying or reading a book. It's interesting to see how 3D, an effect obviously popular in films, has been translated over to still imagery to try and draw in a wider audience in the midst of the 3D revolution. I think this is a really good idea, especially for children, and as it says in the article, the illustrations work well even without 3D glasses. It would be cool to try and do a project using this method in the future. Anyway, I've posted some of the books covers below along with their illustrators...if you've got some 3D glasses maybe try 'em out..do't know if it would work though......enjoy!
