Alex Schranz (Orion Pax on Flickr) built this massive Batcave replica from his horde of Caped Crusader pieces. Somewhere between 800o and 9000 LEGO and a neon blacklight later, the construction houses a Batmobile, scaled-up Batman and Robin figurines, and an artistic interior worthy of Mr. Wayne’s approval. At 68 bricks tall on a 40×40 stud base, it’s nearly big enough to host a visit from Barbie-turned-Selina Kyle. (OK, not really, but you can’t blame a girl for trying to sneak Catwoman into the secret lair.)
