Luxury audiovisual brand Bang & Olufsen (B&O) has just announced a pricey wireless speaker, the $999 BeoPlay A6. The style evokes the back of a chair, gently curving and covered in designer fabric from Danish studio Kvadrat. Apparently, this isn't all about looks, though. B&O says its unique shape "enables sound to fill an entire room whilst creating ambience in multiple areas of a house." The interface for the A6 is pretty interesting too. It's all based around swiping and tapping the top of the speaker. A swipe right, for example, turns the volume up. Holding the center mutes, and a quick tap skips the track. Perhaps not the most intuitive control scheme ever, but a cool talking point nonetheless.
