I really liked Clay Shirky's essay on the relationship between physical space and creativity. It's one of those classic, Shirkian riffs that includes a bunch of seemingly glib and merely clever ideas and culminates with a thing that ties it all together and makes you realize that a bunch of stuff you've been taking for granted is REALLY important and a bit weird.
In this video of his talk at PSFK CONFERENCE NYC, Clay Shirky talks about the work of Interactive Telecommunications Program (ITP) at the Tisch School of the Arts at New York University. After working there as an assistant professor for almost ten years, Shirky describes five student projects that he thinks are pushing the creative boundaries - from interface design to how people cluster to build new work. At the end of the talk, the technology thought-leader compares creatives as members of a philharmonic orchestra and wonders if any rules can be drawn from looking at such an ensemble.
