I made one of these so called little black eggs. Take a weber grill and cut the bottom out of it, hook up a turkey fryer burner. The lid has some modifications. A piece of aluminum to create a low ceiling and a vent in front. Add a couple pizza stones and you're in business. I fired it up for the first time yesterday and was pleased with the results. I have a little tweaking to do still but here is my first pie. Not bad, i have heard these things have quite a learning curve due to the intense heat.
