Rockworks.us. Pretty neat idea that's related to my line of work. Sort of along the lines of Habitat for Humanity but they are using "Roadies" (that's right, those roadies) and other folks employed in technical fields in the entertainment industry to assemble prefab houses and other buildings quickly and efficiently.
Actually the concept makes quite a bit of sense. Roadies skill sets include, electrical, carpentry, structural, and quite a few other things that are related to building construction. Not to mention that Roadies are capable of assembling virtually anything in a very short period of time, anywhere in the world.
The project is currently setting up base camps in areas affected by the recent hurricanes and working along with FEMA and local laborers to get going on semi-permanent housing and medical facilities.
