We try to keep the Star Trek references to a minimum (it's just
too easy, you know?), but we're not sure it's possible to write
about the CirculaFloor, a movable floor that lets someone with a
virtual reality helmet walk in any direction while remaining in
the same place, without making at least a passing mention to the
holodeck. We're having one installed here at Engadget HQ
tomorrow.  [Thanks, Sean]
