Shoal
St Davids, Cardiff

An architectural light based piece that uses specially developed software that relates generative swarming algorithms to human and environmental inputs, generating spatial lighting behaviours. Basically a virtual shoal is influenced by the environmental effects on the building.

The individual 'light fish' like it cold. Wind pushes them around the facade, pressure and temperature influence the way individuals seek and follow, external sound births a new 'light fish' internal sound causes the array to progressively get brighter. Male elements colour rotates clockwise and female anti-clockwise, colder it is the more saturated the colour.

Technical Design and Fabrication by Duncan Turner (Carbon Lighting Ltd).
684 individual light engines in 396 fittings (longest lights units are 3.4 meters) hand fabricated utilising a custom contiguous PCB. The fittings are designed to precisely match the changing dimensions of the mesh cladding. In the day they blend seamlessly into the facade. The entire installation was designed to be retrofitted to the existing facade so the lights are also the cable conduit.
1.02 km of light
9 km of cable
250000 LEDs

The control system was developed with Dr Stephen Leary and is optimised to run from an e-book.
