Digital FUN was commissioned to produce an ultra-scale LED video work. The whole work is made of more than 500 square meters of LED display devices inside and three-dimensional glazed surface. Through the principle of refraction of large two-dimensional images, the visual experience of three-dimensional images is created. The work draws on the ink technique of traditional Chinese painting, and conveys the scenes of different four seasons to the audience through the artistic conception of landscapes, birds and animals. As the main reception place of the Shanghai Municipal Government, this project has also become a rare large-scale dynamic video work in China.
