The Louvre is home to thousands of incredible pieces of art, including the Mona Lisa. It’s also home to the Louvre Pyramid, which is turning 30 this year.

To celebrate the pyramid’s 30th anniversary, artist JR created a unique optical illusion that covered the Napoleon Court. Here it is:

All this was created with 2000 strips of paper! Here’s another look, which is even more amazing:

On Instagram, JR talks about creating the images:

“The process is all about participation of volunteers, visitors, and souvenir catchers. This project is also about presence and absence, about reality and memories, about impermanence.”

Sadly, the optical illusion only lasted one day.

This isn’t JR’s first time transforming the Louvre Pyramid, though. Three years ago, he made the pyramid disappear:

What manner of illusion will he create next?!
