The new Lego Batcave is so neat. It is modelled after the original comicbooks and uses the classic blue Batman. Its coolest feature is the Bat-Gear part, where Bruce Wayne turns into Batman. It's so stupidly neat that it's funny.
It's fairly large -- 690 pieces -- and includes Bruce Wayne, Batman, Robin, Poison Ivy and Bane minifigs. The video just shows half of the set, which runs for $US70.
