I made some work about what I called the exterior-interior, digitally as well as hand painted; this I made in Bryce. When you picture a room and you add a window view as well as pictures hanging on the wall, there is no difference between the interior and those pictures, because both are not viewed in stereo. So what is real? What is the difference between the room and the picture on the wall? Only our thinking creates a difference, it says that the room is the whole and the other sceneries are in it. We recognise it as a small room with a window and a chair, the space as a kind of wallpaper on the walls. But the whole room is nothing but a picture on our computer! Where you that sure if there was no little window and no chair? What if this is not a room, but a piece of floor, floating in the open space? That is why I changed a bit the perspective on the wall on the right, to make it more confusing. Tomorrow I will tell more of the difference between window and wall picture, with my next work Encounter of worlds.
