"Designers of Surrealien wrote about their work: “Our conception blurs the border between architectural wall structure and applied interior decoration. Contrary to traditional mural painting, we do not create individual objects of art but generate functions that are adapted to the particular infrastructure of a room.”"
How do they do it?
They have actually created a new wrapping wallpaper technology, when you have to provide a plan of your room, so the Surrealien designers can create a pattern custom made for your home. You can even create your own pattern that will be printed as a wallpaper.
