Pretty amazing! Looks like a parody of Wright.
A lot of wild stuff has accumulated around it. The only thing I can think of that's close is Rock City outside Chattanooga, TN.
from a site I read "Jordan's dad, a budding architect, had been dismissed at Wright's Taliesin home, near Spring Green, with the declaration, "I wouldn't hire you to design a cheese crate or a chicken coop." Soon after, the senior Jordan chose a pinnacle rock south of Taliesin to build a parody of Wright's fancy-pants architecture, a strange "Japanese house." The ceilings were dangerously low (padded now to accommodate tourists) and the structure seemed to cling precariously to the odd contours of the rock."
We went there a number of times when we lived in Chicago. Lots of other stuff added to it (some interesting and odd collections, like automated musical instruments... a la player pianos up to a "player symphony". The house is worth a tour.
