Peddling Something New

Curves can be graceful, opulent, gay or sad. They will form rhythmic patterns if parallel to the picture plane, or describe space if receding from it.
There is no doubt that cycles will continue to improve scientifically, and that tyres and gears will become faster and faster as time goes on. But art, unlike science, does not progress, although the surface aspect of pictures in different periods of time may appear to change. All this would make one think that we had turned full circle. Bikes don't change much, yet artists are always trying to peddle something new.
