These works are a subset of what you see in Interior. The difference is they focus on a smaller space. For example they may focus on studying the relationships and colors and shapes of a few articles on a table. The important thing here is not necessarily the objects but the way the artist is able to convey a feeling of space and spaces between objects. Of course this is happening in all art work, but here it's focused on a microcosm and that allows the artist to work on something that is not changing and so he or she can penetrate more deeply into the relationships.
