A colleague of mine recently sent me a link to a very cool Web site called Whitevoid.com. What makes the site cool is its 3D navigation. The site does a really nice job of maintaining a visitor's orientation from a 3D perspective.
After doing some research I found that this site was created by a German Interactive Art Firm located in Berlin. The site was developed using Papervision3D which is an open source 3D engine for Flash.
Thanks Matt for the link!
