Art and illusion collide, as the French artist JR makes the Louvre's glass pyramid in Paris appear to disappear.

Art and illusion collide, as the French artist JR makes the Louvre's glass pyramid in Paris appear to disappear.?

The 33-year-old artist was invited by the famed art museum, Musee Du Louvre, to create a monumental optical illusion. With paper sheets covering the entire structure, JR's collage perfectly aligns to the architectural backdrop when viewed from a certain vantage point, completely concealing the glass pyramid from view.

It is called an "anamorphic" image and will be visible, or rather invisible, until June 28.
