Green (Ivy-covered) City Building on Flickr

I'm trying to post new blog stuff every two weeks or so. Just can't manage it more often, with all else that's going on in my life.
My friend Eszter Hargittai just turned me on to Flickr. I guess most everyone knows about it except me. Just one of its features is being able to search for photos posted by its members. I looked up "natural building materials," and got 200 photos. Click here to check it out.
Here's a pic from Flickr:
