We feature a lot of LEGO here on Kotaku, for good reason: it's awesome. But the spaceships or Star Wars dioramas we show you are rarely made by kids, or Danish engineers. They're usually made by grown men.

Why would they devote so much time and energy to expressing themselves using what for many is still considered a childhood toy? This great PBS short, called LEGO Art, sticks a camera in the face of LEGO builders like Alex Kobbs (featured a few times on Kotaku) and lets them explain.
