“Rhizome is dedicated to the creation, presentation, preservation, and critique of emerging artistic practices that engage technology. Through open platforms for exchange and collaboration, our website serves to encourage and expand the communities around these practices. Our programs, many of which happen online, include commissions, exhibitions, events, discussion, archives and portfolios. We support artists working at the furthest reaches of technological experimentation as well as those responding to the broader aesthetic and political implications of new tools and media. Our organizational voice draws attention to artists, their work, their perspectives and the complex interrelationships between technology, art and culture. ”
BTW, rhizome is an important concept within cultural theory. The idea is that ideas/culture/things are more like a rhizome than an onion. There is not a centre but nodes of expansion and growth.
