The second biannual IDEAS CITY takes place May 1-4 on and around the Bowery. What is IDEAS CITY? Here's the official description:
IDEAS CITY explores the future of cities around the globe with the belief that arts and culture are essential to the vitality of urban centers, making them better places to live, work, and play. Founded by the New Museum in 2011, IDEAS CITY is a major collaborative initiative between hundreds of arts, education, and civic organizations. This year’s theme is "Untapped Capital," with participants focused on resources that are under-recognized or underutilized in our cities.

IDEAS CITY is a four-day Festival of conferences, workshops, an innovative StreetFest around the Bowery, and more than one hundred independent projects and public events that are forums for exchanging ideas, proposing solutions, and accelerating creativity.

The winner of the 2013 StreetFest Competition is "MirrorMirror" by Davidson Rafailidis. Their installation will be built and installed for the May 4 StreetFest. Here is some information on the winning design from the Storefront for Art and Architecture announcement:
“MirrorMirror” is a base unit covering twelve feet by sixteen feet. The design includes a simple forty-five-degree-angled gable roof made from miorroring panels. A single unit will house small programs. When combined, the units create a large barn-like structure that will can be host to larger gatherings. The design utilizes aluminum frames with Mylar mirror foil that are often used as glassless mirrors in dance studios.
