This (irregular hexagon shaped) house in Japan designed by Katsutoshi Sasaki + Associates features sculptural wooden slats suspended from the ceiling.
The architects maintain this is to diffuse light into the interior from the clerestory windows that wrap around the house - due to it's close proximity to the surrounding buildings.
The beautiful form does create a circadian effect on the structure's surrounding walls - creating a space that is alive.
