3D User Interface
One of the main usages of Indirect3D is creating 3D user interfaces. Here is an example of such 3D UI - 3d calc. All interface elements are made in ind3ds wysiwyg editor. Main program module just recieves messages from components and performs actions in response. Since main program is abstract of ui, different skins can be loaded(we've done 2 skins).
Another thing based on same technology is 3d visualization of 15-puzzle.
Indirect3D is quite ready for anyone to create such interfaces. If you are interested in it and want us to write documentation/tutorials for using ind3ds editor and fastfruit framework, mail me or at least just click here
