Have to say that my favorite picture so far is John deLancie made up as a Borg.
The first time we saw de Lancie as a Borg was for the interactive video boardgame, "Borg Q-uest", which was never released. (Previewed in "The Communicator" magazine.) Footage was shot on the TNG sets, as it had for the previous Klingon interactive video boardgame.
And then came the "Star Trek Borg" computer game (and Audioworks adaptation). Q impersonates a Borg in that production, too. What I don't know is if they reused the footage originally made for the boardgame's video, or started all over again?
