 Kim Song-gun is also called "Painter of the Waves" since he mostly paints sea and river sceneries with thunderous waters.Despite a very realistic depiction the paintings carry a subtle kind of modern abstraction achieved through the dramatic presentation of the waves.One of those paintings, "Waves of the Sea Kumgang", was noticed internationally due to a photo from Bill Clinton's state visit to North Korea in 2009 showing him sitting next to Kim Jong-il with the large green waves painting in the background.
