Torre Agbar (Agbar Tower) is an egg-shapped 38-story tall display of different architectural concepts. One interesting feature of this building isits nocturnal illumination of 4,500 LED devices that allow generation of luminous images on its façade. Also, the outside of the tower has temperature sensors that regulate the opening and closing of the window blinds.
The Torre Glòries formerly known as Torre Agbar, is a tower located between Avinguda Diagonal and Carrer Badajoz, near Plaça de les Glòries Catalanes, which marks the gateway to the new technological district of Barcelona, Catalonia, Spain.

You can see this tower from far away and it is good view point. Personally I am not fan of modern architecture.
I think it's only a bulding wich you can take photos at night, not much more.
