InterSection. Central Sq. Leeds.
The lighting is designed to visually dovetail with the large diagonal glass façade. Two triangles are sited at the top and bottom of the artwork and mirror their axis. This automatically gave a dynamic form between the triangles that relates to the angled glass façade.
The two triangles were then connected with lines of individually programmable LED’s which create complex parallaxes as people move around the building. Reflections of coloured lines integrate the artwork with the building. The space becomes active. To further animate the space the lights are the lines of light are programmed to gently change all the time. Here was an opportunity for a poetic side of InterSection.
The lighting has a seasonal colour palette and changes colour and pattern in relation to local historical events. For example, the Central Sq. site was where the Mallard set off on its record speed steam journey (126mph) and this has been translated into a Mallard Blue swirls of colour at 1.26pm. In 1755 (17.55pm) the streets of Leeds were first lit with oil lamps. Gentle flickering is seen in the lower third of the artwork in yellowy orange. These events change every week throughout the year.
There are 26 special lighting events. 3 of these events are selected each day. Every week a different set of special events is programmed so that no two weeks special events are the same. The patterns between the special events change every 4 hours which results in no 4 hours being the same throughout the year.
The seasonal colours change over on the spring equinox, summer solstice, autumn equinox and winter solstice. These days are celebrated with a special event.
We have also programmed special events for Christmas day, New Years Eve and New Years day.
Here is the list of historical events which we took as our cue to make 5 minute special lighting events related to these historical moments.
