THere certainly is. There was Millard Tawes(wrote a book
called Creative Sculpture) from Maryland who put a two and a
half ton ferrocement diplodicus in his front yard (now sadly
gone) a 28foot hand hammered sheet aluminum American Eagle
above his garage and an 18 foot high statue of Chief Crazy
Horse in front of the dinosaur(sold and now in front of a
restaurant somewhere on the way to Rehobeth Beach in Delaware
(i have pictures if anyone needs them).When death claimed him
in his late eighties he was hard at work on a twenty foot
high statue of the emperor Constantine the Great(he did a
wonderful wooden model of it).

Incidentally the man who did the "Throne of the Third Heaven
of the Nations Milennium General Assembly" is James Hampton
and has to be seen to be believed. Talk about Grand design.
Portions of it were exhibited in The Museum of Fine Arts in
Washington D.C. (S.I.)(Is it still on exhibit?).It is
pictured and described in Elinor Lander Horowitz,
Contemporary Folk Artists. Lippincott: Philadelphia and New
York, 1975.  pp. 127-132. Words fail me to describe this
great masterpiece of "environmental(?)" art. Hampton's
immense effort was still incomplete at his death. It was
housed in a garage and fortuitously saved.
