A photo provided by the Atlanta Journal-Constitution shows Atlanta police officer T. R. Coxe removing painted material of a large swastika featuring a likeness of Republican presidential candidate, Donald Trump, along the northbound Buford Highway Connector just south of the Piedmont exit, in Atlanta, Georgia, USA, 09 December 2015. Just days after Donald Trump's call to ban Muslims from entering the United States, someone painted large swastikas featuring the Republican presidential candidate's face on at least two northeast Atlanta bridge supports. The symbol, which includes a cartoon of Trump sporting a Hitler-like mustache, was painted along the Buford Highway Connector. A second, similar image was found on a concrete bridge support on nearby Piedmont Road. Trump said in a statement released on 07 December that there should be a total and complete shutdown of Muslims entering the United States. (Photo by John Spink/EPA/AJC)

Women perform square dancing at a park square in Beijing, China, April 9, 2015. Chinese-style square dancing is running circles around other hobbies for the elderly, with millions taking to parks and plazas across China, swivelling their hips and rolling their arms – but it's not to everyone's liking.

“Snailpimp” is a project by artist Stefan Siverud, who is having fun decorating living snails with the most varied designs, from the McDonald’s logo to the miniature lighthouse through Pac-Man, Ikea and Adidas. A funny and interesting project, achieved with non-toxic paints, which of course raises the question of the impact on these living animals. If some people ironize that these highly visible snails are less likely to be inadvertently stepped on by people, others point out that they are more easily spotted by predators… A project in line with the Inner City Snail artist Slinkachu.

Luis Hernan was always curious about how wireless technologies like radio are transmitted through the air. So after finishing up his studies in architecture, computer science, and design, Hernan decided to research these invisible signals through a PhD at Newcastle University. Hernan set up a system that turned the wireless signals around him into colourful, ghostlike images using long-exposure photography, allowing people to see the strength of the signals around them.

Street art started out as unintelligible words written on concrete walls with spray paint by gang members or silly kids. Now, however, it evolved into a unique form of art that might stun and inspire awe in the onlookers. For example, the artist that goes by the name 1010 specializes in creating optical illusions. His creations look like portals into other dimensions, without any hint that it might simply be a flat concrete wall painted over with multicolored paints. These pieces of art are so good that it is hard not to reach out into these ‘holes’ to find out whether or not they are real. (Photo by 1010)

You have no idea of the power of a skillful makeup artist. By working his magic, he can transform a woman into a respectable gentleman, a young lady into a heartless drug dealer, or simply show how a person would look like after a few decades have passed. Some can even transform a not-so-handsome young man into a beautiful young girl, which can spell a lot of trouble if you see him/her at a night club. Lucia Pittalis is one of those masters of makeup, and she uses her skills to stun the audience by transforming herself and a few volunteers into famous movie characters, actors, and musicians.

During dull lectures 19-year-old Jody Steel, from Boston, America, likes to draw on her thigh. Using pen she creates stunning temporary masterpieces – and now her doodles have given her internet fame and job offers from around the world. Even her lecturer is a fan – instead of punishing Jody when she was spotted doodling on her leg in class, the lecturer commissioned her to illustrate a book she was editing.

A cenote is a natural phenomenon, a sinkhole in the Earth’s surface. The Yucatan Peninsula in Mexico has an estimated 7,000 cenotes because it is primarily made up of porous limestone. For millions of years, rainfall slowly ate away at the limestone and a huge system of underground caves and caverns was formed. Many filled with water from rain or from the underground water table. When the roof of a water filled cave collapses, a cenote is born. The water found in a cenote may be fresh water, salt water, or both. Structurally it may be completely open, like a lake, almost completely closed with just a small opening at the top, or somewhere in between.
