One of this man's works is separated by a large gray band and depicts the titular poem overlaid on colored squares. This artist of Once Emerged from the Grey of Night painted a cluster of colored arches in Viaducts Break Ranks. The story of the foolish Anselmus in The Golden Pot inspired him to paint Tale a la Hoffman, and he painted an orange sun hovering above the black outline of a roof in a work of "twentieth century pointillism," (*) Ad Parnassum. This man's notebooks were collected into a major work of modern art theory, and his best-known work features four bird-like stick figures who perch over a pit on the hand crank for the titular contraption. For 10 points, name this Swiss-German expressionist who taught at the Bauhaus and painted Twittering Machine.
