The Infinite Dungeon Corridor. Enter at your own risk...and inevitable peril. Ow! I think I jammed my finger on a mirror!
An infinity mirror gets the dungeon treatment in ThinkGeek's latest intermingling of optical illusion and medieval fantasy trope. The desktop-sized corridor will distract and enamor you for hours with its seemingly unending walls of flickering torches, user-adjustable to 3 levels of brightness. The recursive fun is also backed for wall-mounting, though this method of display makes it more difficult to incorporate the dungeon into action figure game nights.
Infinite Dungeon Corridors operate on 3 x AA batteries.
