The Graduate School of Design is featuring a display on "The Evolution of Housing Concepts: 1870-1970" in the lobby of its home at Gund Hall. The exhibit, co-sponsored by the New York State Urban Development Corporation and the Institute for Architecture and Urban Studies, is composed of models and drawings on the history of high-density housing projects, and it includes descriptions of works by leading international figures such as Le Corbusier. All of this may sound rather dry and pedological, but GSD exhibitions are almost always well produced.

The Busch is putting a lot of its permanent collection of 20th century sculpture on public display for the first time in a long time during the summer, and it's worth the trip over because you may not see some of this fine collection again for another long while.

Be-ing Without Clothes is a good way to be, especially during these God-forsaken Cambridge summers, and it's also the name of a very fine exhibition of contemporary photos at MIT's Hayden Gallery.
