High Five: 5 artists that make you look twice

Which one of these two hot dogs is real? Howard Lee knows how to draw objects with such precision that it's almost impossible to distinguish between the drawing and the real item. He films the process and uploads the video onto Youtube. By now, the British artist has almost 130,000 followers. And just so you know, the hotdog that's real is the one on the left.

It looks as though artist Silvia Wald has a particular passion for meat products. Well, almost. What the staunch vegetarian loves much more than real meat are plush toys or pillows in the shape of sausages, bacon or ground meat. Her Berlin "butcher's shop" offers more than 40 such artworks, such as the sausage neck pillow or the chicken leg cuddle pillow.

This artwork shows the entrance area of the London's shopping square Covent Garden as though it had broken in the middle into two parts. The installation, created by British artist Alex Chinnek in 2014, is held together by a cleverly devised steel construction. The artist uses his art to speak to people who don't usually visit museums.

Dutch artist Leon Keer has an unusual talent for working with different perspectives. He creates fascinating three-dimensional paintings on streets. He first designs the pictures on his computer before transferring them onto the ground. As is the case with all 3-D paintings, the three-dimensional effect only works if you look at the picture from one particular spot.

These optical illusions have been created by using precise body painting and a black background. Mirjana Milosevic, called Kiki, transforms herself and others into body paintings. It's not an easy task for the makeup artist. During the process she can't breathe. Otherwise, the painting becomes blurred. The Serbian artist presents the process of transformation on Youtube and Instagram.
