Since shadows emerge from the interaction between light and things, they are evidence of something being material not just abstract. Shadows can thus be tools through which to understand the relationships that humans form with different concepts and objects. Chanbyul Park combines material research of shadows with scientific, historical and intuitive research into metaphysical concepts such as time and light.
In the past, there was the only one light source, the sun. It means that there was only one shadow. These days, however, human has invented artificial light sources, the light bulbs. Now we can see tons of artificial light sources and tons of shadows anytime, anywhere. Shadows arise according to the number of light sources. One light has one shadow, and two light sources have two shadows. The shadow is a great tool for facing the world we live in.
