Having a big TV in your living room means dealing with a huge black box when it's off. Normally, at least. Bang & Olufsen's Beovision Harmony hides 77 inches of LG-powered OLED display behind its integrated speakers. When it's time to watch something, the screen raises up while the speakers fold outward, with the process going in reverse when you power it down. On display at Milan design week, it will be available for purchase this fall.
