Looks good in that light, as you say. There are some quite interesting ATC towers about. There are also some eyesores, like the current tower at LHR. One of the more unusual, and IMO likeable ones, is the tower at Finland’s Helsinki Vantaa airport. I guess it’s very much of a case of the beauty being in the eyes of the beholder in topics like this.
