It's interesting that "ugly" comes up as a form of valid argument against the ArcelorMittal Orbit (and let's just go with "Orbit" from here on out. I die a little inside each time I have to type that name.) For the most part, people expect art to be by turns ugly, strange or beautiful. But when it comes to architecture, all of that changes. No one wants an ugly building, and strange won't win many fans either. And one thing that seems most unsettling about Orbit is that it occupies that uncanny zone between being sculpture and building. As a sculpture, it could easily have been planned on a much smaller scale and had a similar, if not identical, effect. But as a kind of building it feels rather purposeless and self-aggrandizing. There is of course a great history of self-aggrandizing art and architecture out there, so that can hardly be held against it.
Well, maybe it can a little.
