Modern 3D Plus Sign Icon Rotation

This visually clean and contemporary animated icon features a 3D circular emblem in vibrant purple and white, centered on a stark black background. A prominent plus sign is elegantly integrated within the circular form. The icon executes a smooth, continuous rotation on its vertical axis, showcasing its glossy, metallic textures and dimensional depth. This polished animation is ideal for applications requiring a clear, engaging, and modern symbolic element, such as UI designs, interactive presentations, or branding materials where a dynamic 'add' or 'positive' action needs to be conveyed with sophistication.
