Dae-Kwan Kim believed he could express the river running through his mind if he put some colors on the a pane of transparent glass as water let the light penetrate itself. It is light that makes water look transparent, and that penetrates substances of water. Glass has similar quality to water even though different substances constitute these two things each other. Light works as a medium in making water and glass have a lot in common. The artist aims to awake our senses to perceive water and recognize light at the same time through his glass paintings.
