The case's designing concept was based on two Eastern imageries, "Huangshan's sea of clouds" and "Japanese snow scenes". With "fluid" linear as the main design, it combines the abstracted symbolic brushwork in Oriental landscape paintings. The imagination is left blank for users to extend while resting in the space. The designer created shapes with natural solid wood, applicating smooth curved lines and large-scale collages on the ceiling. The large-scale of the top with a sense of line interprets the flowing movements of floating clouds.
