Over at Instructables, you can find out how to make just about anything. I've been collecting a list of interesting food-related projects. This one is: Make pizza with a plasma cutter, a backhoe and a pile of mud! One of the great things about this particular Instructable is how the author, Fritz Bogott, talks about many of the inspirations and deviations that he took while on the path. There is some good use of reclaimed materials, some techniques sustainable and not, and a whole bunch of pictures. To view the detail shots of the photos, you'll need to make an account and sign in. I don't know that I can convince Melanie to let me go ahead and try to make this one, but it seems like a great way to enhance the back yard.
