I just watched part of this on IFC the other night:
http://www.garbagewarrior.com/

It's a documentary about an architect who builds beautiful, functional homes out
of old tires, bottles, etc. and basically out of pre-used materials.

The documentary covers a lot of different topics. First it shows the homes he's
built and the unconventional people he works with. Then it shows the battle he faced
with the Taker establishment in the form of the New Mexico government (who
basically told him "there is only one right way to build"). Then it shows him
heading to Asia to help build simple, practical homes for tsunami victims.

Definitely watch this if you have not done so already! The guy is a real character,
and it's a classic taker vs. leaver struggle.
