Completion is near on Monaco's tallest skyscraper ever, and its first new one since the 1980s. Fueled by a luxury-housing boom in the tax-haven nation, the Odeon Tower's so-called Sky Penthouse is expected to sell for more than any other apartment in the world has ever sold before.

One glance at the 3D models created by Rebeca Puebla is enough to realize that this artist has a soft spot for BDSM. The finely detailed model of a nun with heavily tattooed hands and a ball gag in her mouth or an Asian woman in a latex suit of a horse leave no doubt about it. At first, Rebeca Puebla has started out as a traditional illustrator. However, in later years she became a 3D character artist for films, TV, and video games. Though she has many regular-looking 3D models and illustrations, many of her works are quite controversial featuring 3D models of ladies in latex suits or wearing Nazi uniforms.

The artworks that Alexa Meade makes are very unique and original. A usual painter creates a 2D or a 3D drawing on flat 2D surface. Alexa, on the other hand, draws over the body of a regular person, making them look like a 2D painting. The pictures of these people are almost uncanny, as you realize that the eyes “paintings” are real, and suddenly it dawns upon you that you are seeing a living and breathing human being. It is weird how we perceive this world, and how easy it is to trick our brain into thinking that it’s seeing a two-dimensional object. (Photo by Alexa Meade)

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)

The combination of Venezuela's sky-rocketing prices and chronic product shortages have left many struggling to put regular food on their tables and maintain a balanced diet.

Tim Laman is a field biologist and wildlife photojournalist. His pioneering research in the rain forest canopy in Borneo led to a PhD from Harvard and his first National Geographic article in 1997. Since then, he has pursued his passion for exploring wild places and documenting little-known and endangered wildlife by becoming a regular contributor to National Geographic. He has eighteen articles to his credit to date, all of which have had a conservation message. Some have focused on endangered species such as Orangutans or Hornbills, while others, such as a series of articles on Conservation International’s Biodiversity Hotspots, have highlighted regions under intense pressure.
