THE streets of York came alive when celebrity scientist Adam Hart-Davis launched a light-hearted temporary artwork.

Dancing In The Streets is an interactive light display controlled by the movements of passers-by and is the third creative installation by the Renaissance Project to enliven the city centre.

Dancers from Bretton Hall College, in Wakefield, also took part in the launch, demonstrating how the installation is influenced by its audience.

Dancing In The Streets was developed by York company KMA Creative Technology. Its launch has been timed to coincide with the York Festival of Science and Technology, and it will be switched on every evening from dusk until midnight, until June.

Tom Wexler, of KMA, said: "We have been experimenting with live computer-generated projections, motion-tracking and dance for several years, and we are delighted that we've been given the opportunity to bring all these elements together and make this technology available to the public this way for the very first time."
