Ok, I'm a little confused here. Mainly as to where you saw me use this effect? Could you show me please? lol. Because I don't remember doing what you're describing.

There are two ways to do this and one of them I can't do [:P].
You can either do it in a 3d program and use a movie then overlay the swf movies on the walls when you turn and "face" them.
Or you can just make the hallway get bigger and bigger... In which case you'll need to use vectors (definetly) otherwise the image will get blurred.

I wouldn't really suggest doing either because the first is bandwidth intensive and the second is difficult to do properly, dependant on the speed of the viewer's computer and looks a bit 'rigid'.

Oh and I don't get what you mean by a "Jumping out of the screen type effect."

Can you show us what you've done?
