How to blur or overlay a moving face in video?

Shh! It's all part of maintaining my mystique.

Maybe if there's a 2010 CGA convention, you all could meet me there and find out if I really look like Gordon Freeman or not.

Back on topic: I've abandoned the picture-in-picture projects for the time being. My next PIP video may include footage of Wii Sports Resort (and, of course, footage of me playing Wii Sports Resort).

I think that would probably cause the universe to implode in on itself. Everyone knows Gordon Freeman doesn't play the wii.
