In the last couple days, I've just been amazed at the ideas presented in Earthship Biotechture. It's a really creative way to build homes from things left-over, economical in that it has figured out systems to build the houses, and eco-friendly. They're totally self-sufficient houses - no electric bills, no water bills. They're really innovative ways of living out in nature.

Check out this video and the website if you're interested:

Way cool! It's got me dreaming about the possibility of having a house in nature. :)
