Lots and lots of pictures--a cob oven (they say--see the book--but since it's a temporary structure they felt free to use cob as the only layer) with what strikes me as very wet cob. (although I think that my experience with actually doing cob was with very dry cob.)
And there's a 24 x 24 masonry heater that looks pretty interesting. Takes a LOT of firebrick, though.

There's that rough slab siding that folks were talking about a couple of months ago.
