Yet another entry for the 2009 season of CBC's Dragons' Den, Doc Holloway's invention is strictly for the dedicated (and rich) fans of the flight simulator genre of gaming.  He makes monster cockpit simulators, such as the one embedded below, and he thinks the "accessories" are ready for the mass-market.

I actually wonder whether or not the seat moves in reaction to what's happening on the screens, or if Doc is just shifting his body weight (not unlike what I do when I play WipEout HD) while playing... I can't really find info on that, but an old Wired article for one of his previous inventions states that, yes, the pseudo-cockpit does react to your movements (possibly causing your stomach to react in turn). You can always vote for his invention here, and give him the chance to get the funding he says he needs to put a Cloudwalker in every GameStop in Canada. You could also vote for Mariachi Mayhem instead...
