A plastic parabolic mirror. There was a thread in main about it a while back, dude bought one and in shipping they cracked the mirror on him, snapping a piece off. We debated various methods, I think the guy gave up on it IIRC.
It was only Time Traveler and Holloseum. Very unique games, I would have one if I could find one with an intact mirror. Sits pretty wide, takes up more footage than a standard cab but less than a pin.
