This is the Torre Agbar, a skyscraper in Barcelona, Spain. It was designed by Jean Nouvel and finished in 2005. I'm including it on the blog because of the way it melds 2D and 3D elements. It stands as a stunning piece of architecture by day, but at night it takes on a whole other persona. Built into the facade are 4,500 LED lights, and the building turns into a stunning lightshow. The whole thing is controlled by computer which is able to create 16 million colors and endless patterns of movement. Watch the video!
