You’ve seen the coolest Mindstorms contraptions, now check out the five geekiest LEGO creations. They range from a miniature Batcave to an insane Star Wars organ that doubles as a giant diorama. Continue reading to see them all.

5. Batcave

Weighing in at more than 20,000 LEGO pieces and over 100 pounds, this light-up Batcave diorama by Carlyle Livingston II and Wayne Hussey comes tricked out with the Batmobile, Batboat, Batcopter, Batwing, Batplane, and a few Batcycles for good measure. (It took 800 hours, so mint rides are a must.) Furthermore, the Batmobile spins on a motorized turntable, the wall rack of weapons and costumes cycles, and the Batplane can be lifted for takeoff.

4. Large Hadron Collider

Such news and research has earned the Large Hadron Collider many fans, and one of its biggest is Sasha Mehlhase, a physicist from the Niels Bohr Institute at the University of Copenhagen. Mehlhase has decided to help promote the LHC to students by taking the time to recreate a 1:50 scale model of it using Lego bricks. In total he spent 81 hours creating it, which was split between 48 hours of designing the model on his laptop, and a further 33 hours putting it together.

3. Apollo 11

Some unplaceable Herculean conviction drove LEGO architect Ryan McNaught to build a 5.76-meter-tall recreation of the Saturn V rocket used for Apollo 11 out of 120,000 plastic bricks. According to McNaught, this is the tallest LEGO structure in Australia. Even though this sculpture took 250 hours, Ryan found the time to include the Astrovan and sneak in two droid stowaways.

2. Portal Gun

An employee of the Lego Store in Minneapolis seems to take his job very seriously, as he spent about a year designing this amazing Portal gun, full of truly realistic features. The mix of Lego Mindstorms NXT and Lego Art is always guaranteed to give life to a masterpiece! Originally, the artist built this nearly 2,000-piece Portal gun as part of a costume-play for the CONvergence 2012 in Minneapolis.

1. Star Wars Organ

We took the four most famous Star Wars worlds – Hoth, Tatooine, Endor [Ed’s Note: I’m guessing they meant Naboo] and the Death Star – and built them on to the barrel, accordingly to the musical composition. When the organ is turned, the bricks touch little mechanical sensors – which strike the keys of a keyboard and play the Star Wars main theme.
