Some may look at the following as completely useful or perhaps useless. This is a very interesting structure that is located on top of the ARoS art museum in Aarhus, Denmark and was designed by Olafur Eliasson. This structure is is a actually a 360 walkway taking shape of a ring and what makes it different is that it is colorful, so colorful that it has all the colors of a rainbow.
I think this place is incredible as it shows you the city in a different overlay color depending where you stand. It may be a simple structure but it sure shows you a more colorful Denmark and I believe this place would not only attract tourists, it would serve as an outstanding medium for professional photographers alike.
