Two people are seen walking along an elevated outdoor walkway or bridge. In the foreground, a person wearing a backpack steps onto a long, rectangular digital display embedded in the floor, which is designed to resemble a piano keyboard. As they walk, the "keys" on the display light up in a vibrant array of colors, including red, purple, blue, and yellow, creating a dynamic and interactive visual effect. The person continues to walk along the length of this illuminated piano display. Behind them, a second person, a woman in a long, dark dress, is also walking in the same direction on the regular walkway. The walkway features a metal railing on the right side, beyond which lush green trees are visible, indicating an outdoor setting, possibly in a park or natural area. Large, dark, angular structural beams of an overpass or bridge are prominent above and to the left of the walkway. The floor of the walkway itself appears to be made of light-colored planks or a similar material. The scene is illuminated by natural light, suggesting it is daytime. This interactive art installation is located in Yuzhong District, China.
