Centaur - a Four-wheeled Segway
Mr. Protocol writes "Segway, the folks who brought you the two-wheeled wonder called the IT, have a new concept vehicle up on their website. Called Centaur, it's a four-wheeled version of the IT that pulls stable wheelies by acting like a two-wheeled IT. The movie (Windows Media or Quicktime) shows someone having far too much fun riding one."
