Or maybe, another day, when you walk down the street, you suddenly find a huge coke bottle rolling towards you. And you are not having these nightmares in the middle of the night, with an owl hooting in the background. What do you do?
Look again. These are some insane 3D paintings on the pavements. The paintings above, are the works of Julian Beever, a chalk artist. He uses the concept of anamorphosis to bring such 3D effects.
One other street artist is Edgar Mueller. Paintings like the Lava burst(below), was done in 5 days, working 12 hours a day and his world record painting, the Ice Age covered nearly 330 square meters in Westfield, London.
For the love of anything "art", this cannot be missed.
