Designers adore playing with optical illusions. Some create simple designs with a twist, while others conceive optical effects of a more ostentatious variety. In any case our collection gathers striking designs that tease our senses and are able to totally transform interiors. Whether it is a carpet on the floor with a special layout or a particularly patterned wallpaper or ingeniously cut mirror, designers add a third dimension to normally flat surfaces resulting in amazing visual effects. Manipulating shapes and the way we perceive them works equally effectively in furniture design. Surprisingly shaped beds, bookshelves or chairs are fun and can sometimes seem a surreal element in the interior.
