Pixel-clad shopping centre
"To update the Galleria Mall in Seoul, Dutch firm UN Studio and theatre lighting specialist Rogier van der Heide (working for ARUP) mounted individual LEDs behind 4,340 frosted glass disks, turning a 1970s concrete structure into an ever-changing, light-reactive and computer-programmable facade that behaves like a giant video screen."
Shimmering by day and radiant at night, the disks are frosted on both sides to diminish sun glare and diffuse light produced by LED fixtures behind each disk, capable of generating 16 million colors. Because each LED is individually controlled, together the disks act like pixels on a huge screen, displaying text, scenes, and color schemes changed via the Internet, up to 20 times per second.

thanks for posting the project on your website. The key to the user interface is twofold: the individually controlled LED's can be driven through a computer interface (a screen with a map of the building that you can mouse over choosing colours, rythms and intensities) which is accessible over wireless as well as IP conncections, and secondly, a piece of software that converts any video signal or file to lighting commands considering each glass disk on the facade a pixel of a huge moving image. We uploaded many .avi files that were seamlessly converted to lighting commands by the software, thus allowing an intuitive creation of the lighting program. Architecture: UN Studio, lighting and controls: Arup Lighting. For more info, please call me in the Amsterdam office of Arup, contact details at www.arup.com. Thanks, Rogier van der Heide
The project received the Radiance Award, the most prestigious lighting design award, but little recognition has been give to the dimension that this site addresses, which is the interaction between humans and the technology. The light movements on the facade have been updated several times now and the users are more familiar with the way the system responds to what one puts into it. With the frequent updates, the building has come to life.

Thanks for the additions and clarifications. Looks like a very interesting project.
