Going to CHI?

Anyone out there going to CHI?  It's the Computer Human Interaction conference and this year, it's being held in Paris from April 27-May 2.  I'll be there, participating in a panel session on Gamification @ Work, with Janaki Kumar, Mario Herger, Sebastian Deterding, Scott Schnaars, and Matt Landes.  CHI now asks participants to create short videos as teasers for their sessions, and we put together 2 different versions.  So here's a little gamification for you--let's have a contest and you all tell me which one wins!
