Just watched the clip - very interesting. Is there a statistic to how many users have cameras at their workstation? I know I have one at home, but not here.
I'm trying to imagine an office (filled with cubicles) with 100's of gmail users all using body motion at the same time. I can also envision a commercial promoting this, where everyone is sending and replying to gmail in unison.
You do know this is April Fool's Day, don't you Artashes? Google always does something outlandish on April 1st evey year.
