Recently there has been demand for display equipment capable of advanced expressions in spatial design. For example, there is the Adobe Interactive Wall at Union Square (New York City, 2007), and the Zero Energy Media Wall of greenPIX (Beijing, 2008) using LEDs placed on the whole facade. The simple display of information contents is becoming insufficient, and more appealing spatial designs combining information content with interactive art expression are becoming more important. In this paper, we propose a shape memory alloy motion display (SMD), a novel piece of display equipment taking advantage of the existence of an actual object. Then, we introduce an interactive art work plant based on SMD technology.
