Carlyle Livingston II and Wayne Hussey spent over 800 hours across twelve weeks building this LEGO Batcave. It's made out of 20,000 individual parts, weighs over 100 pounds, and even has its own lighting system.
It's also got a total of four motors hidden inside to power various elements, like elevators, the Batmobile's turntable and a rotating storage area for Batman's outfits and gear.
I'm...it...I'm speechless.
