In this day and age, who's actually got time to locate an opponent and sit down to play a physical chess match? And even if you make it happen, how many moves can you get in before you're interrupted by a phone call, text, e-mail, or a compelling need to tweet "My pawn just p0wned?"
Carnegie Mellon design student SJ Lee's Flip-board Chesstable takes checkmatus interruptus into account, featuring a magnetized board on hinges that can be flipped 180, turning it back into a coffee table while inverting and saving your game. So now when you're losing you can kick your opponent out, citing work, and spread out that copy of Grandmaster Techniques.
