The Picasso and Duchamp sculptures are definitely high art using bicycle parts. However as an art event or exposition of modern Bike art I would prefer rolling sculpture myself and advocate a Art Bike Parade similar to our Art Car Parade, in which any and all forms of rolling cycle art pieces or associated derivatives could participate in order to raise bike consciousness. A special C&V class for the purists would be at it's core. No fossil fuels allowed, but any fossils included (like me).
