"He tweaks my cerebrum," late professor Stephen Jay Gould said of Rockman (7) . His snakes grow legs and chickens sport multiple sets of wings. Kangaroo-sized rats stroll across futuristic landscapes. A pig harbors human organs for harvest, and grossly oversized parasites, ticks, ants, and viruses populate his large surreal scenes. Botanical compositions, swarming with nature's less appreciated creatures and extinct or mutant forms feature aquatic or tree-sized dandelions. Humans are rarely present, though human handiwork always is. Riddles and humor are mixed in with actual soil, mud, sand, vegetation, and other collage materials, adding tactile interest to rich layers of color and varnish, which create a highly finished, luminous effect.
