TV Heads

Switch on and get clued up to the most ingeniously hi-tech but quirky walkabout characters - those terribly British robots, the TV Heads.

Featuring cameras fitted to their helmets broadcasting what they see directly to their own TV screens, the TV Heads can switch between live images and pre-recorded footage that plays on another channel.

But there's no end to the flexibility of these characters and they've successfully appeared as DJs, initially making their light-hearted debut at the world-renowned Glastonbury Festival.
