Speaking of 3D viewing (we were); check out this amazing pop-up version of Alice in Wonderland, by Robert Sabuda. (click on pic at right for larger version.) A 2D web page just cannot do this 3D creation justice :)
The pop-ups in this book are simply amazing. Not only are they marvelous 3D creations that emerge effortlessly from a 2D book, but they are dynamic; the movement of the pictures as each page is opened illustrates the action of the story (for example, a white rose bush is painted red). Each page has a major work of sculpture, as well as smaller books embedded on the page which contain an abridged version of Lewis Carroll's classic (and which have pop-ups of their own!) The rabbit hole is a genuine telescoping tunnel into the earth which must be seen to be appreciated (yeah, it folds out from a 2D page, too). Very cool.
Megan was recently given this book as a birthday present. I'm not sure which one of us is enjoying it more :)
