Mobile sculpture is a type of artwork that is designed to move or be moved. These sculptures often incorporate elements like balance and kinetic energy, allowing them to sway or rotate with air currents or manual interaction. The movement can be subtle or dramatic, creating a dynamic visual experience. One of the most famous artists associated with mobile sculpture is Alexander Calder, who pioneered this art form in the 20th century. His works often feature colorful shapes suspended from wires, creating a playful interaction between art and the viewer. Mobile sculptures can be found in various settings, from galleries to public spaces.
