If you have ever watched a professional table tennis tournament (or Forrest Gump at least) you know that a two-person game can get completely insane. Now, imagine the mayhem that would ensue with up to 12 people battling it out at once. Thanks to designer Guenter Arndt and his modular table tennis system, this ridiculousness is a reality.
Simply put, users can arrange the tables in any configuration that they desire. You can even retro fit a traditional table to add wild new elements to your game. Currently, Arndt's table is up for a Next Big Thing Award for 2008, and a book is in the works that outlines configurations and rules for serious multi-player games. If it ever does go up for sale, all you would need is a really long Foosball table and some 3-player chess to complete the ultimate game room. [Project Page and Next Big Thing via Crunchgear]
