Special Exhibit: Boundaries
Sep Kamvar (MIT Media Lab)

During the Renaissance, artists and writers broke away from the medieval era and explored the expression of the human soul as an individual: its passions, its social disposition, and what it means to live within social constructs. Boundaries explores these age-old themes in the context of the communal soul -- the soul of societies, collectives, cults, and nations. In today's hyperconnected world, Boundaries asks what it means to be an individual. And in today's hyperdigital world, Boundaries asks what it means to be human. Using people as his primary medium and technology as his secondary medium, Sep Kamvar collects and remixes material from the hearts of hundreds of visitors to the exhibition and millions of strangers online, blurring the boundaries between imagination and reality, self and other, observer and observed, human and machine. Works shown in the exhibit exist simultaneously inside the gallery, on the street, and on the web, and each piece is a collaboration between artist and viewers.

Boundaries was created for the Skissernas Museum in Lund, Sweden, where it was on view from September 18, 2012, to April 1, 2013.
