Largest Space Invaders artwork

The largest artwork themed on the Space Invaders arcade videogame measures 150 m² (1,614 ft² 85 in²) and was created by street artists Leon Keer and Remko van Schaik (both Netherlands) at the EPFL campus in Lausanne, Switzerland, on 17 March 2014. The anamorphic artwork, which is 2D but appears 3D to the eye, was created entirely with chalk. It took six days to complete and was on display at the École polytechnique fédérale de Lausanne until 10 April 2014.
