2D on 3D: The new hotness
The WPF3D team have delivered one of the coolest features yet: Fully interactive 2D controls and content rendered in your 3D scene.

This shows a Button and a TextBox wrapped onto a sphere. The 2D controls behave exactly as you would expect, with hit testing, mouse capture, and everything. Very sweet.
