Why is paint on glass animation used?

Paint on glass animation is used for its unique aesthetic and tactile quality, allowing artists to create fluid, organic movements that can evoke emotions and enhance storytelling. The technique involves painting directly onto a sheet of glass and then capturing the images frame by frame, resulting in a visually striking style with rich textures and depth. This method often lends itself well to experimental films and artistic projects, providing a handcrafted feel that contrasts with digital animation. Additionally, it allows for spontaneity and experimentation, as artists can manipulate the paint in real-time.
