Hex, or Hex Media, were a London-based multimedia group founded in the early 1990s by artist Robert Pepperell, coder Miles Visman and the DJ duo Coldcut. The group set out to exploit the creative potential of, what was then, the new media technologies of CD-ROM, multimedia, interactive computing, video sampling and portable video projection.

Working across a wide range of media - from computer games to art exhibitions - the group pioneered many new media hybrids, including live audiovisual jamming, computer-generated audio performances, and interactive collaborative instruments.
