Illusions that make rooms bigger

The American artist Nils Nova has made some impressive art work that locates between optical illusion and curious perception of space. The explanation lies in printing photographs in large format. He is simply taping the printed photos on walls in a room to give the perfect optical illusion. The rooms appear to be much bigger than they are because the photos are showing extra space in such a convincing way. It looks so realistic that you would be fooled to believe that the house or apartment is a lot bigger than it really is.

Something similar has been done by another artist that has made “invisible packages, billboard and street signs” that are also printed photos wrapped around the mentioned to give the illusion of invisibility. (Source)
