Hundreds of ribbon tapes hanging down from the ceiling are moved by the artificial wind blowing through the ceiling fans. The moving image of willow tree is projected on the ribbon tapes and spectators pass under and through the leaves of willow, hearing the sound of locusts' singing. In the work the viewer are engaged in and can feel the moving image of virtual willow tree and wind. This work is based on my own experience of passing under the willow trees on my way school or home.
