This image depicts a detailed section of a large, elaborate kinetic sculpture known as the "Mechanical Tree" or "Crystal Tree," located within the main atrium of GUM (Main Universal Store) on Red Square in Moscow, Russia. The sculpture, a complex assembly of polished metal, clear tubes, and illuminated elements, extends vertically towards a vaulted, multi-paneled glass roof structure, which is visible across the top of the frame, allowing ambient light to pass through. Prominently featured at the upper-center is an irregularly shaped, translucent object, emitting a distinct blue glow. Emanating from this upper section are multiple clear, curved tubes, forming intricate arcs across the upper portion of the sculpture. Below this, several vertical, cylindrical structures, made of clear material, enclose internal ribbed metallic components that are internally illuminated with a warmer light. The lower section of the sculpture incorporates numerous large, curved, and spiraling elements in a vibrant red color, interspersed with reflective silver components. Partially visible on the lower-left are large, white, curved surfaces. The primary materials appear to be stainless steel or chrome-plated metal, clear acrylic or glass for the tubing and cylinders, and either painted metal or colored plastic for the red elements. The scene is well-lit by a combination of natural light filtering through the glass roof and artificial illumination from within the sculpture itself, creating numerous reflections on its polished surfaces. In the blurred background, on an elevated walkway or balcony to the left, several indistinct human figures are visible, observing the installation. Their small size relative to the sculpture provides a sense of the artwork's substantial scale within the multi-level retail environment.
