Stan Huncilman combines child-like playfulness with an ingenious primitivism. He creates a wonderland of intriguing forms and convoluted messages. There is a signpost ahead reading, "Linear Thinking Stops Here." Mr. Huncilman's vade mecum opens the door to an incomparable world of nutritiously puzzling paradigms whose roots may be in religion, folk art, nineteenth century industrialism or Greek mythology. In this world, a whimsical sense of humor walks arm in arm with an obstinate determination to create.
