Sad Snow consists of a 9-sec gif projected on the wall in a loop and a 7-channel sound work installed with 7 speakers on the carpet in front of the projection. Visitors hear a repeated wave sound (10 sec) from different directions of the speakers. Another sound piece (16 min) is programmed to be played every 30 minutes. A voice in this sound tells a story about the moment of meeting dinosaurs that is written down in Korean and English. The text is printed on paper and installed under the Christmas tree as a pile of paper so that visitors can take it to read.
