Something colorful was hung some distance below the ceiling at the Incheon international airport (ICN). At first it looks like a bunch of tiny colorful balloons. However, each one has different shapes and even move up and down.

The name of this interesting artwork is “Hello.”

This work uses Hangeul, a major cultural heritage of Korea, as a model to raise international awareness on the scientific excellence and creative design of the Korean language. The content, delivered by an object comprised of 1,000 Korean consonants and vowels, introduces the diverse travel cultures of countries around the world. With 1,000 Korean consonants and vowels as LED units, this artwork achieves three-dimensional forms and movements by connecting a motor and microcontroller unit to each consonant and vowels to control height and LED color. -By Kang HeeRa
