Invisible Cities is now in beta. The project has evolved from a visualization of collective memory for Taipei to a platform with the capability of surfacing data from the Twitter and Flickr services for any geographic area. While initially we have kept the piece focused on New York City due to the density of available data, we are planning to extend it with other cities as the project progresses. For documentation, please refer to the project site, as well as our recent article in the Volume 3, Issue 1 of the Parsons Journal for Information Mapping (Invisible Cities: Representing Social Networks in an Urban Context).
Many thanks to my collaborator Liangjie Xia for his tireless dedication and remarkable talent, and also to Jason Hsu for the inspiring discourse in the early phases of this project.
