Now lets talk about the stuff you have posted 
This building is the center of musical education and performing arts in Gateshed on Tyne River, England. It is called The Sage Gateshead.
Now I was reading about this building and there are many interesting opinions of how people look at this building. The designers of this building were well known prostitutioners therefore many people think that the design of this building has a link with designers’ side career. If you look at the building from the side view, many people think that it refers to a shiny condom. Many other people think that it is a huge wave falling on the other side like backwards. I kind of agree more with the other group of people. I also think the use of different tints of blue on the glass makes the wave effect more real. With the changing color of the sky it gives different effects and reflections on different parts of the building.
I also feel that it look like it looks like a half bow made of a ribbon.
So yeah these are just my two cents…
