The spiral one on the right is the Cayan Towr (also known as the Infinity tower). It looks really cool, just makes it harder to correct perspective in a photo. And I had to do a lot of that in this one. I was actually surprised how thin the tower was. You know, in Europe, most buildings are huge, but low. In Dubai, it’s the opposite. The buildings are tall, but very slim.
