Artist Alexander Beleschenko was commisioned to design installations for two pedestrian links at Canary Wharf.

The lower ground floor provides access from the Jubilee Line tube station to the new CitiGroup Offices. The ground floor provides a link between the entrance lobbies of the two different styles of the CitiGroup Towers. The challenge for SBT Architects was to create a link between the two different architectural styles to provide visual stimulation and illuminate the space to fall in line with the Group's Public art strategy.

The designs evolved into continuous, full height back-lit walls constructed from panels of opalescent laminated glass with pieces of coloured glass bonded to it. Fluorescent lamps illuminate the panels from behind, each individually addressed by a digital operating system. In addition there is a timed sequence that automatically fades the lights on and off. Through these different variations and intensities of light an appearance of movement is created.
