From the HTTP site:
HTTP is London’s first dedicated gallery for networked and new media art. Working with artists from around the world HTTP provides a public venue for experimental approaches to exhibiting artworks simultaneously in physical and virtual space, and for online projects that explore participative and collaborative art practice. Artists’ projects on DVD, real-time, webcast, software art and live art also play a role in the curatorial work of HTTP.
