“After taking LSD. I lighting up a candle in the middle of the wood and during the 30 secondes of exposure, i make a meditation about the holism of nature surrounding me. Feeling the crystal vibration irradiating from the center of the Gaia mother earth. So in this picture i try to show you the magic, sacred metaphysical quality of the nature and new age bullshiting you”. – Benoit Paillé. (Photo by Benoit Paillé)

If we were to burn NH4Cr2O7 with HgSCN in the Dark Ages in Europe and show it to anyone, it is us who would be burning next on a fiery cross of Inquisition. And it’s no wonder, since this experiment produces a truly marvelous result. At first, as you ignite the mixture of NH4Cr2O7 and HgSCN, all you can see is that it is slowly burning with a reddish flame. After a while, however, a crater is formed in the middle of the burning pile, and then, suddenly, tentacle-like appendages start sprouting from the burning mixture. And you can almost hear the scream of the mad occultist – “Come forth, Kraken! Come forth!” But of course, this is simply a chemical reaction that is called the "Pharoah's Serpent". It was also often sold in firework stores until people realized that it was toxic.

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.

I would like to tell you why many artists, who like me, have painted portraits and landscapes in oils on canvas, worked with acrylics, watercolors, and pen and ink drawings, have turned to the art of gourd carving.

Two Chinese farmers got more than they bargained for when they pulled up the root of a fleece flower – and came face-to-face with the doppelganger of Homer Simpson, on May 17, 2013. The large root appears to have two bulging eyes and a prominent nose – giving it an uncanny resemblance to the famous cartoon character. With two offshoot roots shaped like arms, it even looks like it is pondering or confused – just what you would expect from the real Homer. (Photo by ImagineChina)

As kids we have the natural desire to explore and to create. Whenever our parents would make for us a paper plane, we would become overjoyed seeing it fly across the room. However, planes are not the only thing that can be made from paper, and not only kids are fascinated by it. Some people master the art of origami and are able to create pretty much anything. You never know what’s going to come out when the artist twists and turns a piece of paper in meticulous ways. Finally, the figurine is complete, and you immediately see the striking resemblance of this piece of paper with an animal or some other creature. Ross Symons is one of those artists. He creates his figurines simply for the joy it brings him. Maybe, he uses this as a medium to enter his childhood, or maybe he has other motifs – we will never know. (Photo by Ross Symons)

Scared of Heights. “Taken from the highest residential building in Asia: the Zenith in Busan. This was taken with official permission (which took me months to get) and safety measures were taken. I had to hang myself over the edge to get this shot. Not for the faint of heart! But when you’re at a height like this, the world below you just seems different. It takes away the fear one would normally have, and gives a sense of peace instead”. (Photo by Albert Dros/NatGeo Cities Travel Photographer of the Year 2017)

In Dougie Wallace’s photos of Mumbai taxis, the chatter, yelling, and constant horns of the city are almost audible. A selection of his images is on show at Gayfield Creative Spaces, Edinburgh, as part of the Retina photography festival until 30 July. For four years, the Glasgow-born Wallace focused his photos on one kind of taxi in particular: the Premier Padmini, a 1960s workhorse painted in black and yellow. Locally known as “Kaali-Peeli”, there were once more than 60,000 of them in the Indian city. But thanks to laws restricting pollution, the cars now are fast disappearing from Mumbai’s streets.
