A chalk artist has made spectacular 3D drawings on street pavements and shopping mall floors.
Leon Keer's paintings have been on show in shopping malls in Belgium and Kuwait with one of a hovering green car at Wijnegem Shopping Center Belgium measuring NINE metres long.
His painting in Marina Mall Kuwait shows a maze-like structure.
Leon starts with the outline of the image before turning it into a 3D masterpiece.
Although they are painted on a flat surface, the incredible work appears 3D from certain angles.
His work has taken him all over the world. He's done paintings in Florida, United Arab Emirates, France and Dublin.
Leon, 42, from Utrecht, The Netherlands, said: "Performing as a street painter lets me share the joy of painting with the public.
"For me street painting is about creating memories. I like to experiment with all kind of materials and techniques.
"I work with a mixture of techniques, use a rich variety of materials, ranging from professional acrylic paints to adhesives, solvents, primers and tar. With that, everything could be the canvas.
"I love working together. Together with other artists you are able to create streetscapes as far as the eye can see.
"With 3D street art you are able to get interaction with the public.
"I like the remarks of people passing by. Mostly amazed and 'look at that', and 'Oh I have seen that on internet'.
"Sometimes I am even surprised in how people interpret the painting and trying to figure out how the 3D effect works.
"It always makes me smile to see the open-eyed look on their face."
