Famous Belgium artist Rene Magritte created a painting of his pipe and wrote the title “Ceci n’est pas une pipe” (This is not a pipe) below the image. He wanted to emphasize that the viewer is seeing not a real pipe, just a painted illusion created on the paper. Ray Barkus was inspired by that. By painting the sky on the wall and naming it “Ceci n’est pas un mur ” (This is not a wall), he claims that the imagination is capable of creating a new reality.
