I must say... as much as I like the form of the crystal, the cladding has turned out to be very disappointing. I was willing to overlook the fact that it looks more white than the metallic-looking cladding from the renderings, but the discolouration just looks ugly. Actually, it's not so bad if you're looking at one of the sides at an angle... it blends into a white-grey blur that looks natural. Looking at a side head-on, it just looks sloppy. Everyone I've shown the Crystal to since the cladding began to be applied has asked about the discolouration, and at first I thought it was protective film. Very disappointing to learn this is what we'll be stuck with - I can't imagine Libeskind is happy. Oh well... hopefully with time the contrast will be less prominent. Still a very nice addition, but the execution could have been handled better.
