On the floor, lit by the round-shaped light are spine-like objects. It appears that the light from the ceiling casts shadows of these cone-shaped objects onto the floor. However, when you touch a cone, its shadow starts to move; for example, it rotates around the object like a sundial or expands and contracts. If you touch other cones, you will see a diversity of reactions, such as all shadows starting to move or suddenly becoming colored, as the shadows of individual cones react differently and in combination.
In this work, although they appear to be real, these shadows are created by CG. All objects, except for those that are completely transparent, have shadows. In other words, a shadow proves the existence of an object. However, while serving as a certification of existence, the shadow itself is immaterial, just like images displayed on a monitor or screen. The shadow is the origin of visual media devices such as the shadowgraph and magic lantern. In this work, the shadows create their own world of imagination in response to the active involvement of the viewers. And we are forced to recognize our own shadow and existence as we see the real shadow of ourselves and the fictitious computer-generated shadows on the same floor.
