Located on the lawn in front of the TSMC Building, Leaf (2017) is the creation of the noted Spanish landscape artist Juanjo Novella. This eye-catching piece of landscape art gives the impression of a butterfly getting ready to take off. With a height of 8.7 meters and a width of 7.5 meters, the sculpture is slightly tilted, and weighs about eight metric tons. Made by drilling over ten thousand holes into steel plates, despite its huge mass, it has a lightweight and elegant feel, and only touches the ground at three points. Sunlight passing through the rust-colored veins projects a flowing tapestry of light and shadow. 
This unique sculpture takes on an especially majestic appearance when illuminated by the oblique rays of the rising or setting sun.
