The MIT hacking culture has given us such treasures as police cars and cows on the Great Dome, a disappearing door to the President's office, and the commencement game of "Al Gore Buzzword Bingo." Hacks can be technical, physical, virtual, or verbal. Often the underlying motivation is to conquer the inaccessible and make possible the improbable. Hacks can express dissatisfaction with local culture or with administrative decisions, but mostly they are remarkably good-spirited. They are also by definition ephemeral. Fortunately, the MIT Museum has amassed a unique collection of hack-related pictures, reports, and remnants.
