Joe Coleman (wiki) is nuts: his first drawings as a child were of bleeding saints, death by fire, and stabbing. In first grade, Coleman was placed in a class for emotionally disturbed, disabled, and retarded children. At age 10 he received an art award for a drawing of garbage. At age 12, he set a fire in his elementary school yard and "confessed" to committing several murders to a priest. Check his website here.
