If you haven't ran over to artofvideogames.org to vote on which games The Smithsonian is going to include in their "Art of Video Games" exhibit, the clock is ticking.  Voting ends April 17th.  The exhibit will be on display from March 16th to September 30th in 2012 (so schedule your vacation appropriately) and will explore 40-years of digital goodness in all its forms.  So rush over to their site and vote for your favorite games!  It's a democratic process THAT WORKS!
