best way for iron man 2 type holographic in Game GUI

Hi,
I want create a GUI which is inside the game as a usal 3D Object. The GUI should be part of a scene in which a hologram like (transparent) or thin glass panel is levitating.
The planed GUI shoould act like the holograhic interface in iron man 2.
The GUI Tutorial look like a 2D interface which is not prt of the game. Is it possible to
project a default GUI ( with custom styling ) on a side of a transparent game object (like a levitating block of glass or a glass pane) or is the standard GUI not suitable for such kind of ingame GUI’s.

What is the best way to implement such a GUI.

best regards

Andreas

This has been answered before here: Can I use UnityGUI to make a 3D GUI? - Unity Answers

The basic consensus is that it can not be done properly with Unitys GUI. They also link to a forum where they discuss the issue.

I would myself recommend using NGUI from the asset store. It supports 3D GUI fully, but it is vastly different from Unitys GUI and is not free though.
