Attention!

To be able to see the 3D content on

Internet  Explorer 4 and later you should use: 

Netscape Navigator or Communicator version 3 and later, you should use: 

plug-ins.

You may already have these plug-ins and not be aware of it.
I would suggest following on to the next page,
if nothing meaningful appears, coming back to this page and choosing the approprpriate plug-in.
