The Hausmannian Building on Georges V Avenue in Paris, France has been referred to as the ‘melting building’. Referred to as trompe l’oeil (trick the eye), it’s actually a mural and an optical illusion that appeared in 2007. The old building needed restoration work but instead of contemplating the scaffold, a creative solution was found. Artist Pierre Delavie made pictures of the building in its original form, and then the images were distorted by a computer program and printed on large canvases, which completely shut down the facade of the house. Frederic Beaudoin pasted over the image of the foam cornices, and distinguishing reality from the picture has become very difficult, especially at a distance.
