The Planetarium Projector Museum is home to the world's largest collection of old school planetarium projectors. Museum owner Owen Phairis (who, when he's not overseeing his collection, plays Nikola Tesla in an electrical stage show called "Man of Lightning") has been obsessed with the machines ever since he visited the Hayden Planetarium as a child (rather like somebody else we know).

According to the folks at Cool Hunting, who put this video together after visiting the museum in Big Bear Lake, CA, "These fantastic optical relics have been rescued from defunct planetariums and schools, now taking residence under a re-purposed military parachute in Phairis' space."

Color us captivated.
