Architecture that repairs itself?

Discusses the beginnings of "living" building materials, other known as "protocells", creating limestone structures from the bottom up. Considering how my last post made a point of the influence of natural elements in public places, this recent video is a great example of how some people see buildings in a similar way. But instead of staying with the decay aspect, they are pioneering the creation part.

Color me extremely impressed. I am very delighted to see this technology being pursued.
