The final project for Digital Day Camp '09 took the form of a "Pop Up Party." What follows is a description of the process of the making of the DDC09 Pop Up Party. Over the course of one week, DDC09 researched and explored the Highline – asking ourselves questions about what it once was, what it is now, who built it, for who – by interviewing people on it, and people who live and work nearby, including those who have never checked it out, and never plan to. We considered everything we had learned, and using all our skills and resources developed of the course of this summer, we decided to design a guerrilla, public intervention.
