We need a 3D cube transition slideshow

Please see a dummy page at http://cogent-design.com/clients/project/philosophy.html
This is a slideshow with 2 slides; please click on “Discoveries” and “Philosophies” to see the 3D cube transition. Each slide pictures has lots of hotspots that will link to different pages. It crucial to not to loose this function.
We want 2 things to be changed:
1. To be able to link to the second slide from a different page. The link should be something like this: http://cogent-design.com/clients/project/philosophy.html?slide2
2. Also, with the current transition people are looking at the cube from the outside. Our client wants this to look as if people are inside the cube (please see a visual at http://cogent-design.com/clients/project/cube2.jpg). He wants a transition like “Box” for PowerPoint 2010 (please see attached). If you haven’t got PowerPoint 2010, please watch http://www.youtube.com/watch?v=AnsGSwMlxy4 and skip to 0:47. I have already contacted the person who wrote the existing script and he said that the new transition needs a completely new script. So, we really need somebody with experience in Javascript animation.
