The so-called MegaFaces Pavilion, sponsored by MegaFon, consisted of 11,000 telescopic cylinders, each of which represented a pixel. As on a pin screen, the cylinders could extend to form the shape of the faces, and LED lights at the ends of the cylinders added the proper color and shading. The data for the 3-D faces was generated in 3-D photo booths inside the building.
