Art Goes Underground

Stockholm (Swedish pronunciation: [ˈstɔkːˈhɔlm, ˈstɔkːˈɔlm, ˈstɔkːɔlm] ( listen the second one)) is the capital and the largest city of Sweden and constitutes the most populated urban area in Scandinavia. Stockholm is the most populous city in Sweden, with a population of 851,155 in the municipality (2010), 1.37 million in the urban area (2010), and around 2.1 million in the 6,519 km² (2,517.00 sq mi) metropolitan area (2010). As of 2010, the Stockholm metropolitan area is home to approximately 22% of Sweden's population.

Founded no later than circa 1250, possibly as early as 1187, Stockholm has long been one of Sweden's cultural, media, political, and economic centres. Its strategic location on 14 islands on the south-central east coast of Sweden at the mouth of Lake Mälaren, by the Stockholm archipelago, has been historically important. Stockholm has been nominated by GaWC as a global city, with a ranking of Alpha-. In The 2008 Global Cities Index, Stockholm ranked 24th in the world, 10th in Europe, and first in Scandinavia. Stockholm is known for its beauty, its buildings and architecture, its abundant clean and open water, and its many parks. It is sometimes referred to as Venice of the North.

T-Centralen (Swedish for "The T-Central"; T being an abbreviation for "tunnelbana", the Swedish word for "underground" or "subway") is a metro station that forms the heart of the Stockholm Metro system, in the sense that it is the only station where all three of the system's lines meet. That, its central location, and its connections with other modes of transport make it the most used metro station in Stockholm. The station is located in the Norrmalm borough of Stockholm, between Sergels torg (Sergel's Square) and the street of Vasagatan.

On a normal day, some 219 000^{[citation needed]} passengers travel to or from this station. It is connected by a pedestrian underpass to the neighbouring Stockholm Central Station across Vasagatan (for national and regional trains, and the Stockholm commuter rail network) and to the Cityterminalen long-distance bus terminal, making it easy to continue a journey started by metro train.

When opened on 24 November 1957 the name of the station was "Centralen" ("The Central"), but it was renamed on 27 January 1958, as the metro station often was mistaken for the central railway station to which it is connected. T-Centralen has two separate sets of platforms, connected by a long moving walkway on a mezzanine level.

The Stockholm Metro (Swedish: Stockholms tunnelbana) is a metro system in Stockholm, Sweden. The first line opened in 1950, and today the system has 100 stations in use, of which 47 are underground and 53 above ground. There are seven lines numbered from 10 to 19, in three groups identified by a color: the Green, Red and Blue lines. Each color line has two or three numbered lines on shared sections through the Stockholm City Centre.

The 105.7 kilometres (65.7 mi) long metro system is owned by the Stockholm County Council through Storstockholms Lokaltrafik (SL). The operation is contracted to MTR Corporation.

A mural is any piece of artwork painted or applied directly on a wall, ceiling or other large permanent surface. A particularly distinguishing characteristic of mural painting is that the architectural elements of the given space are harmoniously incorporated into the picture.

Motion blur is the apparent streaking of rapidly moving objects in a still image or a sequence of images such as a movie or animation. It results when the image being recorded changes during the recording of a single frame, either due to rapid movement or long exposure.

Blue is a colour, the perception of which is evoked by light having a spectrum dominated by energy with a wavelength of roughly 440–490 nm. It is considered one of the additive primary colours. On the HSV Colour Wheel, the complement of blue is yellow; that is, a colour corresponding to an equal mixture of red and green light. On a colour wheel based on traditional colour theory (RYB) where blue was considered a primary colour, its complementary colour is considered to be orange (based on the Munsell colour wheel).

In Modern English, "blue" is one of the basic colour terms, and one of the seven spectral colours, intermediate between violet (purple) and cyan. It comprises a considerable number of identifiable subcategories that can be identified with descriptive terms like navy blue (a dark blue), cyan blue (or "blue-green", on the boundary to the green range), or sky blue (azure).
