After I read the (original) article, I contacted the cafe. After a few attempts, I got through and spoke to an employee who knew nothing about the chandelier (incomprehensible to me, but taken in-stride). They indicated that they would have someone who knew get back to me. Never happened. I just read about Parans and have contacted them. I am trying to get this implemented at Patagonia, but would like specifics before I run it up the flagpole; "expensive" is not too useful.
