Elusive Signs: Bruce Nauman Works with Light is one of those art exhibitions you will want to spend hours in, and you will not be able to, because it will give you a headache. Both impulses are right on: The seminal artist
Bruce Nauman's neon works from the 1960s to the 1980s, including the masterpiece
One Hundred Live and Die and the parallelogram-shaped room with green light that
makes you look like death, are gorgeous, rich, and agonizing. No pleasure without pain. (
Henry Art Gallery, 15th Ave NE and NE 41st St, 543-2280. 11 am—5 pm, $10 general, $6 seniors, students free.)
