I just received a link to The Eco Zoo site and quite honestly this is a step above what we might normally expect from a web site. Using
Papervision a custom 3D engine in a slick fashion, switching between 3D environments, the tree/world and the pop-up book specifically, the site explores some exotic creatures.
There’s a lot of attention to detail throughout, from the butterflies fluttering around the tree and the simulated cloth to the leaves at the top blowing away and the pop-up book pages which you can rotate around and discover the artist has even taken the time to draw the reverse of the characters in the scene.
Superb site, check it out here.
