uBrowser : 3D Web Browser

Normally you use a two dimnsional flat browsing, how would you like to browse in 3D? uBrowser lets you browse in 3D!

“uBrowser is an simple Web Browser that illustrates one way of embedding the Mozilla® Gecko rendering engine into a standalone application using LibXUL. In this case, the contents of the page is grabbed as it’s being rendered and displayed as a texture on some geometry using OpenGL™. You are able to interact with the page (mostly) normally and visit (almost) any site that works correctly with Firefox 1.5.”

You can download a pre-built Windows version of the uBrowser application or get a package that contains the source code for the Windows version of the uBrowser application and build it yourself.
This is an illustration of how to embed the Mozilla Gecko rendering engine and they claim it will be very useful once fully integrated into the Second Life client.
