Artist JR recently created an optical illusion using the famous Louvre Pyramid in Paris, France - one of his largest projects to date. Using gigantic slabs of paper with the Louvre Palace printed on them, the artist and his team covered the glass pyramid entirely, creating the effect you see below. A pretty simple and cool idea executed to perfection (judging by these images, this was no easy task). Scroll down for more images and click here to follow JR on Instagram.
