A poster by street artist Aaron Li-Hill as part of the "Brandalism" project is displayed at a bus stop in Paris, France, November 28, 2015, ahead of the United Nations COP21 Climate Change conference in Paris. Brandalism is a revolt against corporate control of the visual realm. Following on in the guerilla art traditions of the 20th Century and taking inspiration from Agitprop, Situationist and Street Art movements, the Brandalism project sees artists from around the world collaborate to challenge the authority and legitimacy of commercial images within public space and within our culture.

“Dover Castle is a medieval castle in the town of the same name in the English county of Kent. It was founded in the 12th century and has been described as the “Key to England” due to its defensive significance throughout history. It is the largest castle in England.

The outbreak of the Second World War in 1939 saw the tunnels converted first into an air-raid shelter and then later into a military command centre and underground hospital. In May 1940, Admiral Sir Bertram Ramsey directed the evacuation of French and British soldiers from Dunkirk, code-named Operation Dynamo, from his headquarters in the cliff tunnels”. – Wikipedia

When you think of the People's Liberation Army, you probably don't think of line dancing. But the Chinese military's latest online recruiting video makes a soldier's life look more fun than the macarena. The brief spot, posted last week on the website of the Ministry of National Defense and going viral, features tanks and fighter jets, as well as soldiers dancing in rows to a quirky hit tune by the Chopsticks Brothers called “Little Apple”. Its lyrics include, “You are my little dear little apple/I can never stop loving you”.

The illustrations created by Joao Carvalho are not just simple 3D drawings. By making it look as if various characters were drawn on regular note book paper, Joao fools our minds into thinking that the flat objects we see on the picture are actually 3-dimentional. To create these pieces of art, Joao first draws the lines of the “notebook” paper already bent, as if they stretch over the object that is about to be drawn. Then he applies shading and his masterpiece is all done! By looking at his pictures it is almost impossible to view them not as simple 2D drawings, but as real 3D objects. (Photo by Joao Desenhos)

A Santa Claus taking a selfie on a surfboard is seen in the yard of a home in the Sleepy Hollow area of Torrance, California, United States, December 15, 2015. In many neighborhoods of Los Angeles, homeowners compete for the most lavish and creative holiday light displays. Torrance's Sleepy Hollow is one such neighborhood where every home outdoes the next: surfing Santas, life-size nativity scenes, ferris wheels, and giant inflatable snowmen line the lawns on every street.

Beneath the Swedish capital lies an intricate web of underground train lines. More than 90 of the 100 stations in the 110km tunnel system, sometimes referred to as “the world’s longest art gallery”, have been decorated with paintings, installations, mosaics and sculptures by 150 artists since the 1950s. After spending a couple of weeks exploring arctic Norway and Sweden, London-based travel photographer Conor MacNeill headed underground to capture images of the metro stations.

Karl Bang's paintings are unique because he combines totally different styles of painting within the same format. It is very difficult to design a balanced composition with realistic elements that are juxtaposed with flat colors and patterns. The faces of his subjects are painted realistically in the Western tradition with subtle gradations of color; while, his figures and costumes vignette into abstracted shapes, lines, flat colors and patterns that reflect Karl's background in China. It is as though there are different visual languages being spoken within his paintings.
