There's a good run of glass up on the second floor, south side. It was after dark when I saw it, but my impression honestly wasn't positive. It is curtainwall, but the wall is broken up by lots of mullions, and there are two strong horizontal bands running along the elevation so it's broken up that way as well. The mullions don't seem to follow any sort of pattern either, so it's like the wall has just been broken up into dozens of smaller windows for no apparent reason (well, other than that two small windows are cheaper than one large one).
The banding also looks kind of cheap and dated. It was hard to see in the dark but I think they're using stainless caps (either that or I was just seeing the silver of the aluminium pressure plates)
