Dutch artist Suzan Drummen‘s large-scale floor installations are mesmerizing and complex circular patterns made out of mirrors and brightly colored glass. The fractal-like arrangements feature ornate and elaborate circles growing exponentially out of each other and vibrant rings of spiraling colors winding into the surface of the floor. They are composed of crystals, chromed metal, precious stones, mirrors and optical glass. A sensory experience, and visually stimulating, the glittering installations play with the architecture of the space — climbing up walls and sweeping across the surfaces — examining the idea of illusion and optical effects.

Underwater photographer Alexander Semenovs has snapped some of the most stunning, fragile life forms anywhere on planet Earth. Shot in deep, dark conditions, the images continue to provide an insight into what lies beneath, with glowing creatures appearing a lot like aliens in the pitch-black water. Semenovs has shot the likes of bioluminescent jellyfish, aggressive-looking worms and many species that leave a lot to the imagination. The 30-year-old from Moscow does the majority of his work in the White Sea, near the Arctic Circle. Here: A Comb jelly – Beroe cucumis. (Photo by Alexander Semenovs/Caters News)

These pictures show a rather annoying crow irritating an eagle. The crow tirelessly circles the bird of prey and repeatedly lands on his head – much to the crows displeasure. The encounter was spotted by Greaves Henriksen in Tamilnadu, India. The 52-year-old amateur photographer believes the eagle was sitting close to a nest, which the crow was trying to defend.
