Spotted this on Fran’s blog, to cool:

Bruce Mau’s The Bureau of Doing Something About it: A pop-up studio, working in real-time, designed solutions in response to complaints.
Last year, the Toronto Complaints Choir, produced as part of the 2010-2011 World Stage season at Harbourfront Centre, collected over 1000 grievances, gripes, and annoyances from people across the city. The choir transformed these troubles into a siren song for the disenchanted.
Across twelve days in July, Bruce Mau Design (BMD) worked to do some-thing about it. A pop-up studio, working in real-time in the Propeller Centre, designed solutions in response to the complaints. A book of these ideas was simultaneously designed, and then given away throughout this city we love.
This interactive, cross-disciplinary design event invited Toronto to turn our problems into possibilities. A mix of ingenuity, creativity, (many) mistakes, exploration, and optimism will get us there.
