In Brief

Ingenious design uses friendly neighborhood animals to drive moving artworks.

Bill McHugh of Pennsylvania pursues a very interesting hobby. He has built various mechanical wheels that are literally operated by squirrels and birds in his neighborhood. One of his inventions is the “Swirl-A-Squirrel”, a large wheel mounted on a pole whose outer ring is in the form of a mesh-lined cage. A few peanuts, thrown inside through a small opening, attract the squirrels inside the wheel to make it a squirrel-propelled whirl-wheel. Another sculpture of his called “The Hitchcock” uses birds and a reservoir of water to set its wheels in motion.
