Clay Animation, also known as stop-motion animation, is a technique where objects made of clay are manipulated and photographed frame by frame. Each slight change in the clay model is captured in a still image, and when these images are played in sequence, they create the illusion of movement. This form of animation has been used in various films and television shows, such as Wallace & Gromit and The Nightmare Before Christmas. Artists often use armatures, or internal supports, to help maintain the shape of the clay figures while animating, ensuring they remain stable throughout the process.
