We aim to provide an installation work that children can play with their body in the outdoor exhibition spaces provided by the SODA Museum. We designed a playing art with fresh vibrant colors; Pink and White. The Cloud Forests is an installation that caters to people of different generations, so all ages can appreciate its design; Adults living around enjoy it as an art object and children play with it. This site area is located in the outdoor exhibition space surrounded by concrete walls with openings. The installation is mainly composed of three materials: pink flexible height bars, white balloons, and aluminum wires. First, the pink flexible bars are planted into the ground varying in levels of density. The super dense areas allow only small children to fit through and play in. Whereas, the less dense areas are wide enough for parents to walk through and supervise their children. Next, the specially designed white balloons are placed on top of the pink flexible bars. These balloons are not directly connected to the bars, but each one moves independently. Between the balloon and the bar, there is a layer of wire so that the balloons do not fall onto the floor, but the movement of children and the touching of the bar will be transmitted to the balloon, causing it to move. This project had a very low budget, $4000. We were selected as the winner of this commission project, so we needed to design, install and periodically maintain its status for six months.
