Tom Torluemke is a really interesting guy who paints really provocative paintings. I remember once stumbling upon an exhibit of his that was thinking about race and exploitation of resources that consisted of an entire room lined with panels and then also creepy cut-out wood forms painted black that looked like humanesque oil-demons. He's scary sometimes, but he's usually right.
A website (not Tom's own) says this about him, and it's a pretty good summary:
Chicago-area artist Tom Torluemke creates color-saturated, surreal images loaded with grotesque, sexual and scatological themes without being completely repulsive.
