The infinity mirror trick is as old as time, but the folks at ThinkGeek have come up with a fun new application that will appeal to Dungeons & Dragons fans who find themselves stuck at a desk job during the day. Peering down the seemingly unending hallway of this miniature Infinite Dungeon Corridor leaves you wondering what quests, treasures or mythical beasts lie at the end.
But of course it's all an illusion, made possible by a mirror and a pair of reflected flickering torches with three adjustable brightness settings. And instead of magic, a trio of AA batteries is all you'll need to bring this portal to life. [ThinkGeek]
