From Rhizome Artbase

Visual Rhizome is a thesis project by Aaron Siegel for the degree of BFA in Digital Media Art from the CADRE Laboratory for New Media and the Art & Design department of San Jose State University. is a highly regarded database of new media art work, constantly updating and evolving its collection. It continually adds new artists and their work, each one tagged by keywords, terms, and genres. This project is an attempt to visualize the associations between artists work utilizing the very keywords, terms, and genres applied by the artists themselves.
Users can navigate the database of artwork by exploring the different relationships, or simply by browsing the works by date they were added. This is a useful navigation technique for people seeking work of a similar nature, work done within a particular timeframe, or artists seeking collaborations on a particular subject.
