This companion website for a PBS documentary about Hans Hofmann includes all the essential information about Hofmann, whose reputation as a teacher almost eclipses his reputation as an artist. Wonderful site for exploring how artists influence each other. Includes an excellent biography, many, many examples of his work, and an interactive feature that lets you play with Hofmann's "push and pull," technique for creating the illusion of depth using color and shape. A special section probes Hofmann's legacy through the reminiscences of his students.
