Some people think of trolls as nothing but savage beast, yet others realize that beneath their rock-hard skin hides a gentle kind heart. Ivar Rodningem is one of the people who knows the true nature of trolls. Though these creatures look unruly, it is just the way they were born. Trolls come in all shapes and sizes. Some are small, some are large, and some are simply enormous. They help each other out, though elders tend to be loners, preferring the company of their own thoughts to anybody else. You shouldn’t run for your life if you ever meet a troll, though we wouldn’t recommend pestering them, as they are mighty strong, even the little ones.

How sure are you of your geographical knowledge? Buzzfeed recently put Americans’ geographical knowledge to the test with a survey in which participants had to write in countries’ names on a blank European political map. Unfortunately, they didn’t fare too well, but some of their responses are hilarious (or hilariously mis-informed). But don’t be so quick to judge Americans – when Buzzfeed posted a similar survey testing Brits’ knowledge of the 50 United States, they also came up short. On the one hand, knowing a country’s states is different from knowing independent countries, but on the other, some U.S. states are larger than some European nations, and some U.S. states have larger economies than some European nations.

Few things are more beautiful than puffy white clouds floating in the bright blue sky. Do you remember the time when you would lay on the soft green grass, look up at the sky, and try to recognize shapes in the clouds floating overhead? Wasn’t it wonderful, just lying there, letting the wind caress your skin, as you imagine that the clouds in the sky are actually mystical or not-so-mystical creatures? Dragons, ducks, teddy bears, dinosaurs, everything was up there. It was good old times. As adults we forget about simple pleasures of life. However, an Argentinian artist Martin Feijoo didn’t forget those times, and took them a step further. After imagining what a particular cloud looks like, he draws that particular shape over the picture of the cloud, allowing the entire world to see what goes on in his mind. (Photo by Martin Feijoo)

Dan surrounded by seven days of her own rubbish in Pasadena, California. If you've never thought about how much rubbish you throw away an honest photographic series will open your eyes. Men, women, couples and families with young children have been photographed lying on their backs surrounded by a week's worth of their own rubbish – from old cartons of milk, used nappies and even tampons. The startling series “Seven Days of Garbage” by Californian photographer Gregg Segal is an unforgettable reminder of the amount of waste a human collects in just seven days.

Runner-up. “The City of London, looking towards the Royal Exchange and the Bank of England. The ever-changing London skyline provides many excellent opportunities for cityscape photography, none more exciting than the ebb and flow of traffic at night”. (Photo by Mark Caldon/The Guardian)

Photographer Gregg Segal travelled the world to document children and the food they eat in a week. Partly inspired by the increasing problems of childhood obesity, he tracked traditional regional diets as yet unaffected by globalisation, and ironically, found that the healthiest diets were often eaten by the least well off.

Exhilaration beyond imaginable, intense concentration on a single point, and complete freedom of soul – all these things very accurately describe the art of highlining. Highlining is a branch of a new sport called slacklining, which involves walking on special webbing secured between two points. Andi Lewis is one of the most famous slackliners in the world, particularly due to his performance during Superbowl Halftime Show in 2012. He never fails to surprise people with an amazing stunt or a project. This time he and his friends have created a completely incredible hand-knitted hammock located hundreds of feet above the ground. Just getting to this hammock requires immense skills and bravery. But once you’re finally there, you can rest a while, before mustering up the courage to go back across a narrow line with nothing but thin air beneath your feet.
