In June 2010, two designers had the idea to build a floating swimming pool in New York City's East River, which would also filter 500,000 gallons of river water each day. It may sound farfetched but 1,200 supporters and more than $40,000 in Kickstarter pledges later, + POOL is on its way to launching in 2015. Join Huge and the founders of + POOL as they discuss how design can transform cities and improve the environment, and how dreams can become reality with the power of social media and crowdfunding.
