Inside the ACB. "Realm of Fear" [TNG] shows what it looks like - lots
of blue and silver sparkles. If you mean from an outside observer's
point of view, you're either in one of the pattern buffers, or in
transit to the beaming coordinates. In "The Gamesters of Triskelion"
[TOS], Kirk and crew are lost during transport. In the technobabble
that follows, Spock and McCoy discuss whether recovering the lost
crewmembers from the transport beam, thought to be zipping away from
the Enterprise, is possible. This means that if the beam was somehow
suspended, a smart computer could reconstruct the pattern and beam you
back in. This might be what happened in "Realm of Fear" [TNG]. If the
ACB environment is similar to a plasma field, the bugs could act as
stabilizers. Long shot, but hey.
