We were at Starbucks' World Headquarters to meet a friend for lunch. We waited for her in their test concept, Reserve. This was the display wall opposite the coffee tasting counter made up of dozens of labels in copper holders. Quite the impressive, even if in reality it is one big marketing display. I got the sense it changed regularly as people passed by and moved one or more of the swiveling holders, but we were not around long enough to see for sure.
