light and shadow art

Kumi Yamashita is officially the ruler of the world of light and darkness. She can use them to create very special art. She can make a sculpture when not really making it. Well, if you don't put the appropriate lighting on items which she used you won't see the work of art. She uses random object and then put them in a correct places. Later she must just switch the light on. But to not make it that easy, there must be only one light source and the room where the sculpture is must be perfectly shady. Completed artwork is a connection of physical objects and non phisical light and shadow.
