Chroma Streams; Tide and Traffic a site-specific
artwork for the Kingston Bridge in Glasgow,
Scotland, was designed by Light Projects with architect Ian Alexander, and completed in 2005.
It is a syntactical structure into which the chance pattern of traffic and the predictable
tidal cycles of the Clyde are visibly presented - and interpreted - through an ever-changing,
radiant color montage. As traffic pours into and out of Glasgow city centre the interactive artwork
feeds back nighttime rhythms of city circulation to onlookers and passersby. A multitude of vantage
point perspectives, from cars and riverside pedestrians, combined with the color-changes, offers
unique spatial views of the bridge and river. Chroma Streams
uses light to illuminate and
give resonance to the bridge's overlooked surfaces. Two monumental concrete arcs make up the
Kingston Bridge. Leni has selected the Bridge's underside --its visible parallel connection-- and
its riverine reflection as "the canvas" of her illumination project. Directly under the bridge,
the connective linear fascia frame color-flow patterns which overlap in the middle.
The artist's mutable palette selection and highly orchestrated programming allows for 144
sequences of unique color mixes. Physicist Lord Kelvin's curvy nineteenth-century Clyde River
tidal graph was the starting point of the lighting armature design. Two stainless-steel standards
-which are approximately six meters high - are sleek daytime sculptural elements. Heightening its
rapport with the flow of the River Clyde beneath through Chroma Streams'
series of shifting and
evolving real-time patterns, the installation explores the relationship between the flow of
traffic on the bridge itself and the slow change of tides.
