While I'd love for Waldman to bring the Swing Project to New York (I'll have to settle for a pop-up piano) he's headed next to Bolivia. You can learn why he choose Bolivia and, if you'd like, contribute to the project via Kickstarter. (I did!)

Perhaps you'll be inspired to hang a tree in your front yard to encourage neighbors and passersby to enjoy a swing!
