What is the popular nickname for the Cloud Gate sculpture?

The popular nickname for the Cloud Gate sculpture is "The Bean." This title comes from the sculpture's shape, which resembles a large, reflective bean. Designed by artist Anish Kapoor and installed in Millennium Park, Cloud Gate is made of polished stainless steel, which reflects the surrounding skyline and creates interesting visual effects. The nickname has become widely accepted by both locals and tourists due to its whimsical nature and the sculpture's distinct form.

The use of "Bean" captures the essence of the artwork in a way that is both playful and descriptive, making it easy to remember and recognize amongst the city's many architectural landmarks. The other terms, while describing various aspects or interpretations of the sculpture, do not carry the same widespread recognition and affection as "The Bean."
