We've seen our share of impressive digital signage, but this mall in west Seoul takes the idea to the new level. The wall is peppered with individual LEDs behind 4,340 frosted glass disks to diminish sun glare and diffuse light produced by LED fixtures behind each disk. The wall is capable of generating 16 million colors. Each LED is individually controlled and the disks act like pixels and can display text and color schemes changed via the Internet, up to 20 times per second.
