Create a clean vector-style abstract circular logo on a white background. The logo is made from three curved crescent / swoosh shapes forming a dynamic rotating circle around an empty circular center. The overall shape resembles a spiral or cyclone made of thick curved blades. One large crescent shape starts at the upper left, curves around the top, and tapers to a sharp point on the upper right. A second large crescent shape starts on the right side, curves downward and around the bottom, tapering toward the lower left. Between them is a thinner green curved swoosh following the same circular motion, visible mainly along the inner spiral path. The composition should feel balanced, smooth, and symmetrical in motion, like two opposing curved blades wrapping around a central circular hole. Use a simple flat design with no realistic shading, no gradients, no shadows, and no 3D lighting. Colors: - outer upper-left crescent: solid black or very dark charcoal - outer lower-right crescent: solid light gray / silver - inner curved swoosh: vivid emerald green - background: pure white - center opening: white Style: minimal vector logo, smooth bezier curves, sharp tapered ends, clean edges, modern corporate identity, abstract swirl symbol, circular composition, high contrast, flat colors only

The image shows a black and green circular logo with a white background. The logo is composed of a combination of black, white, and green colors.
