Backball chair lets you mouse by the seat of your pants

While we can't quite picture it improving your Counterstrike game very much, the design-minded folks at Interaction Architecture seem to think that this so-called "Backball" chair of theirs can do its small part to improve human-computer interaction nonetheless. Basically a giant trackball that you sit on, the chair is apparently specifically intended for use in public spaces like airports, although we're sure there's a least a few folks out there that'd ditch their non-trackball ball chair for one of these if they were available to the general public -- which, as you might have guessed, they aren't.
