Recently while watching INE CCIE DC Nexus Class, Brian McGahan over here :
http://www.ine.com/all-access-pass/training/playlist/ccie-data-center-nexus/nexus-hardware-architecture-100121011.html
He showed Cisco 3D product catalog application. While the application was originally designed for IPAD and IPhones. I found that application is also available for Desktops. All you need to do is to download one application first to open the catalog and second the catalog file itself. Both files can be find here:

Similar sort of application is also available for Cat 6500
