The application of data visualization in public art attracts increasing attention. In this paper, we present the design and implementation of a visualization method for sunlight data collected over a long period of time. The proposed method makes use of the Saturation and Value information of collected sunlight data in Hue Saturation Value color space to show the variation of the mood of the sunlight. Specifically, we create visual patterns with two rotating gears, which has an intuitively consistent geometric meaning with HSV color space and the planetary motion. Due to the variation of the sunlight data over time, the generated visual patter presents a periodic variation that corresponds to the changing mood of the sunlight. Furthermore, we also use the sunlight data to generate music as another form of data representation. Two public art works have been created with the above visualization and auralization methods and displayed on an exhibition.
