^Jsome1- flickr/cc license Straight out of the Flinstones, this house consists of a roof, windows, door, and chimney inside a large boulder. I don't know if the stone is real or fake, it seems to be some sort of composite material. The cavernous interior is candle lit with simple log platforms and furniture. Large windmills spin nearby.
Seems dorky at first, but it actually brings up some very interesting issues, on the value of the "modern stone-age family."
