Serenity and Legos??

Someone built an amazing 7-foot long model of Serenity out of LEGOs. It is to scale to work with a Firefly minifig crew. And it has interiors of the bridge, the sleeping quarters, the dining hall, and the cargo bay. And a detachable shuttle! Here's my question - where do you get the Firefly minifig crew? Did this guy build them himself?

Regardless, this is a-frakking-mazing.
