One thing that is great about America is garages.  Inside those garages the inveterate American tinkerer is alive and well, and in  this case, cranking out Gatling guns (pun intended).  Buying a Gatling gun is incredibly expensive, so the patrons of Gatling Gun Forums focus on building their own guns, and there is plenty of helpful info in this regard.  The most interesting section for me is the Progress section, where builders show the state of their build at the moment.  Some pretty nice work.

Lego's minifigures have gone crazy. As small simple figures intended to accent the Lego brick system playsets, they have morphed into a huge profit center for Lego, besides creating an ecosystem around them supporting myriad other companies to scratch the minifigure itch. Lego themselves have made 4 billion minifigures, and other companies, such as Brick Arms, have made large numbers of custom figures.

Legos are not just for kids... Brick Arms was founded in 2006 to produce WW2 themed minifigures and weapons. The demand hasn't slowed down a bit, and collectors clamor for more. They make weapon packs that feature almost any weapon, and their figures are constantly being updated, with one of the latest, Shaun UK Zombie fighter, catering to the Zombie craze.

Lego battles populate YouTube. One of my favorites is from Dino5500's channel, and follows the movie "Stalingrad", even down to arming only one in five Russian Lego soldiers. They should call Brick Arms for supplies.
