Black in White – Magnetic in Paper is an interactive installation engaging with people's hand gestures, which using materials paired with technology. The piece was trying to convert traditional Chinese landscape ink painting to computational form, by focusing on simple intangible interactions to representation complex tangible "Xie Yi"(Freehand) painting.

The charm and life of Chinese landscape paintings is not only the external appearance of the paper but also the invisible, sensible rhythm beyond the pen and ink. However, the traditional form of Chinese landscape painting enables the artist to express their emotions through brushstroke on paper. Most of artist's emotions are shown in a freehand way, and the penetration or spread of ink on rice paper sometimes reveals a surprising style. My work changed the traditional material ink by replacing it with magnetic powder. During the movement of the magnetic powder, traces are left on the rice paper; this is a new portrayal expression of the material. At the same time, the leap motion controls the movement of the magnetic powder according to the gesture of observers. I hope that my work can redefine people's feelings about Chinese landscape painting and observe its charm in black and white.
