First up, here's Mario interacting with people live at E3. Behind the scenes look comes after the jump...

Apparently, Charles Martinet, the voice of Mario, can do this remotely. And when I say "remotely" I mean he's doing it from his home. In this next vid, he explains how he can see people, how he can deliver his voice to the Mario character where they are, and how the software just animates Mario talking on the fly. How freaking cool is that?

Update: Both vids have been removed and I've been unable to re-locate them. Oh well.
