French artist Thomas Lamadieu, also know as Roots Art, must really love looking at the sky, but for different reasons than you might think. Every time he looks up, Thomas sees a potential canvas where the building rooftops frame the sky. He photographs it and uses the odd sky shapes to create whimsical line drawings.

The work of Singapore-based artist Keng Lye could easily pass for some nice photos of sea life – except that they’re not photos, but three dimensional photorealistic paintings! Keng achieves the 3d effect similarly to 3d printer – he pours a layer of resin into a bowl and paints it with acrylics, layer by layer revealing more and more of each creature. His painting technique is almost the same as Riusuke Fukahori’s, but Keng found a new twist to it – he made his creations protrude from the surface.

What may look like an example of Photoshop trickery was actually created by throwing some high powered glow sticks into the waterfalls of California. Using long exposure that would range from 30 seconds to 7 minutes, San Francisco-based photographers Sean Lenz and Kristoffer Abildgaard transformed the waterfalls into nocturnal underwater rainbows.

Canada-based photographer Matt Molloy brings sky photography to a new level. By stacking hundreds of separate sky shots he is able to achieve an incredible brush-like effect. Each final picture in his “Smeared Sky” series is a result of combining from 100 to 200 photographs.

You may think you’re looking at a bizarre painting, but look closer, and you’ll realize that it’s actually an anamorphic 3D sculpture. The massive portrait of Malian actor Sotigui Kouyaté is the latest work of French artist Bernard Pras. It was created entirely out of recycled materials such as clothes and rags, wood, glass lanterns, dishes, rubber and other trash Bernard would gather from the installation site.

Where Children Sleep presents English-born photographer James Mollison’s photographs of children’s bedrooms around the world. The differences between each child and his or her bedroom are striking: Kaya in Tokyo, whose proud mother spends $1,000 a month on her dresses; Bilal the Bedouin shepherd boy, who sleeps outdoors with his father’s herd of goats; and the Nepali girl Indira, who has worked in a granite quarry since she was three.

Scottish photographer George Logan and retoucher Tony Swinney let’s you imagine what it would be like if your cat wasn’t just a purring ball of fur. As a part of “Big Cat, Small Cat” ad campaign for Whiskas, they created a series of funny images showing tiny domestic cats chasing after antelopes, zebras, elephants and doing other “big cat” stuff.
