Bibliodoptera, by Peter Torpey and Elena Jessop, graduate students in Media Arts and Sciences Location: Corridor along the Hayden Library Courtyard (map) A cloud of vellum butterflies, newly emerged from the chrysalis of MIT’s diverse library pages, floats above in the corridor between the Lewis and Hayden Libraries.
