It is a 3-dimensional art creation and a city in Alabama. What is it?

This single word connects the delicate world of kinetic art with the rich history of the American South. As an art form, a mobile is a type of sculpture characterized by its ability to move, driven by air currents or a motor. The term was famously coined by artist Marcel Duchamp in the 1930s to describe the innovative, hanging creations of Alexander Calder. These pieces consist of carefully balanced components that rotate and shift, creating an ever-changing three-dimensional work. The pronunciation, "moh-beel," emphasizes the concept of motion inherent in its design.

Simultaneously, the same word identifies a major port city on Alabama's Gulf Coast. Founded by the French in 1702, Mobile is Alabama's oldest city and has a deep and varied history. It is also known as the birthplace of America's Mardi Gras, a tradition it established even before New Orleans. Unlike its artistic counterpart, the city's name is stressed on the second syllable, pronounced "moh-BEEL." This distinction in pronunciation is a key part of the wordplay, linking two completely unrelated but fascinating subjects.
