: That would be easy, just have the PB on an extremely thin, fast-moving
: platform in front of the terminal, triggered by a polygon the player must
: cross to approach it. As the player walks onto the trigger, the PB
: "turns into" (as far as the eye can tell) the terminal.
: What use would this be at all, though?
I did just think of an interesting use for the same trick, mixed with some others. Replace the PB with an AO animated texture of code paging by on a terminal screen. Put a compiler in front of the terminal, so that it looks like he is actually compiling. Then, when you walk up close enough to disturb the compiler, the real terminal is revealed with a plain logo, as though the compiler had 'logged off'.
