Artists in light at the end of their tunnel vision set over four inyes

Two foot tunnels that were transformed by lights and sound into art installations will return to normal tomorrow, after baffling, intriguing and irritating pedestrians.

Artists Tanya Harris and Goldberry Broad will dismantle the works erected two weeks ago in the Greenwich and Woolwich tunnels, underneath the Thames in south-east London, and begin planning their next art venture.

The two friends, both 23, spent months of talking to Greenwich council, carrying out safety tests and satisfying the authorities that no one would be at risk, before they were given permission for the project.

They worked with sound artists Simon West, James Boxall and Giz Flotations to create the effect of a heart pounding in an artery in Greenwich, and the blue-green sensation of being underwater in Woolwich.

"We would have liked more dramatic effects but we had to water it down, particularly in Greenwich, so the security cameras still worked," Ms Broad said. "But we are satisfied with it in terms of the effect it's having on people."

Although public reaction has been mixed, a council spokesman said: "We had to ask them to turn the lights up, but we're very happy to let them use the tunnels."
