The one I like best is the Mushroom House, Cincinnati designed by architect and design tutor at that state's university, Terry Brown.
Influences at first glance were straight Jabba the Hutch. But for sheer elegance there's the Floating Castle in the Ukraine which is US Midwest farm vernacular via Terry Gilliam and that flying ship with the midgets. Whatever, you start thinking why, in the midst of white walls, strip windows and piloti, officially favoured Modern Movement buildings included Mendelsohn's Einstein Tower, Corb's Ronchamp, the work of Herb Green, Bruce Gough and Paolo Soleri, plus Utzon's Sydney Opera House. Not a straight line amongst them. .
