(LECTURE) Every few years, the Henry Art Gallery commissions something big from a living artist, and Maya Lin: Systematic Landscapes continues the tradition. Lin's talk sold out weeks in advance, but seats are still available for a live video simulcast that will play in a room nearby. Her exhibition opens April 22. Whether she's practicing public art, architecture, or museum installation, she is still obsessed with the land, still the Yale senior dreaming up an astounding gash in the earth that gave the victims of a bad war a good ending. (Kane Hall at UW, 616-9894. Lecture at 7 pm, $5–$10 video simulcast tickets are first-come, first-served and go on sale at 6:30 pm.)
