Survival can become a challenging task in the wild – especially if you’re smaller or slower than your possible predators. This is why many animal species have developed different ways to camouflage themselves throughout the course of evolution. Here are 20 amazing examples of animal camouflage. Can you find all the animals?

This may sound like a science fiction story, but American artist Heather Dewey-Hagborg recreates people’s faces from the DNA she finds on various objects tossed away in the streets. For Heather, an old chewing gum or a cigarette butt has the potential of turning into a 3D portrait of someone who used it and didn’t bother to look for a trash bin.

Minnesota-based artist and writer Ron Miller got curious about what the night sky would look like if the Moon was replaced with any other planet from the Solar system. To grasp the difference better, he replaced the Moon with 7 other planets, keeping them at the same distance as the Moon is from the Earth (which is around 240,000 miles), and did not alter the size proportions of the planets.

One of the nicest and surest ways to flatter a person is to compliment their eyes, but have you paid much attention to the eyes of the animals? Armenian photographer Suren Manvelyan created a gripping Animal Eyes close-up photo series, which is a truly eye-opening experience! His pictures reveal the sort of vibrant colors and intricate details that would even make for a beautiful poster, and seeing something that’s hidden from the naked eye is always the beauty of macro photography.

We already wrote about Brusspup and his crazy anamorphic illusions – and now he’s back with new tricks! This time he attempts to bend water using an audio speaker set to produce a 24hz sine waves. His first video, testing the principle, made it look as the water was going upwards, but now Brusspup has taken it up a notch and actually makes the water flow in shapes and patterns!

Germany-based photographer Martin Rietze gets himself into life-threatening situations to make some amazing shots of volcano eruptions with lighting. Surrounded by poisonous gas and bubbling lava, he photographed the Sakurajima volcano in Japan, and NASA chose his shot as the Astronomy Picture of the Day for March 11, 2013. The winning shot was taken in January.

To celebrate the Science Day in India, Mumbai-based graphic designer Kapil Bhagat created a series of minimalist typographic posters featuring the names of famous scientists. Each design cues to an invention, a theory or an achievement that the scientist is known for. For example, Newton drops an “O” to illustrate gravity, a massive “C” in Copernicus reminds us that he figured the Earth was actually round.

Have you ever wished you could lift your pen off the paper and draw in the air? Sounds crazy, but now now you can! Peter Dilworth and Maxwell Bogue from Boston-based company WobbleWorks have created the world’s first 3D printing pen!

A greeting card-maker by day, Alan Friedman pursues his true passion once the night falls – he sets up his special gear and starts making some fascinating pictures of the Sun right from his backyard. Buffalo-based astronomy lover uses a small (3 ½” aperture) telescope with a Hydrogen Alpha filter and an industrial webcam to capture the surface of the Sun, which looks surprisingly calm and fluffy in the final version.

After seeing lots of anamorphic illusions you get really bored about this whole thing. Yesterday, however, a friend of mine showed me a video titled “Amazing Anamorphic Illusions” that just blew my mind. A master of such illusions, going by the Brusspup nickname, posted this video just two days ago and it already has more than 2 millions views.

People have been applying prosthesis to help the handicapped ones ever since the Egyptians – but probably only recently we realized, we’re not the only ones suffering the pain on Earth. Check out some inspiring examples of the how people have helped the animals by fitting them with a prosthetic needed!

If your hobbies range from food to art to science, they might seem incompatible at first – not to Caren Alpert, though, who combined all of those and presented some stunning microscopic food photographs. The series, called Terra Cibus, were created with an electron microscope, which helps to reveal the side of our food we don’t normally get to see.
