For the April cover shoot of Interview Magazine, photographers Mert & Marcus (Mert Alas and Marcus Piggott; Mert (from Turkey) and Marcus (Welsh from the UK) are one of the premier photographers in the world) captured the stunning Keira Knightley in an attractive black and white photo spread. Rocking pieces from Louis Vuitton, Balenciaga, DVF, and YSL, Knightley looks hot and seductive with a cigarette hanging from her boldly painted lips.

Salar de Uyuni (or Salar de Tunupa) is the world's largest salt flat at 10,582 square kilometers (4,086 sq mi). It is located in the Potosí and Oruro departments in southwest Bolivia, near the crest of the Andes, and is elevated 3,656 meters (11,995 ft) above mean sea level. The Salar was formed as a result of transformations between several prehistoric lakes. It is covered by a few meters of salt crust, which has an extraordinary flatness with the average altitude variations within one meter over the entire area of the Salar.

A man takes a picture of part of what is set to be the UK's largest street art project on August 19, 2011 in Bristol, England. The See No Evil art project on Nelson Street in Bristol will see several multi story buildings in the street covered with art over the coming days. Organisers hope that the project, which has involved top graffiti artists from all over the world, will become a major tourist attraction for the west country city, often said to the spiritual home of Banksy.

(fos) is the name of the first ephemeral installation by the multidisciplinary team (fos). It means light in Greek and melted in Catalan. In this project has been represented by a skin that covers both vertical and horizontal surfaces. The protected façade of the vegan restaurant Rayen at Lope de Vega street in Madrid has been illuminated for 4 days and nights by more than 250lm of yellow duct tape, painted décor items, pineapples and... a lamp. A visual game between perspective and colored volumes that gained the looks.

Italian pencil artist Marco Mazzoni‘s work goes far beyond technical perfection. His representation of historical healing women is enigmatic and sublime. Often leaving the eyes blank or covered with an abundance of birds, butterflies and flowers, he gives the impression of a deeper inward focused sight, as well as obscuring the identity of the individual. Many female healers in the past – both medicine woman and midwives – were brutally persecuted by religion, some even burnt as witches… Mazzoni’s work captures their deep connection with nature and their innate power and femininity with delicacy and beautiful detail.
