Create a 3D abstract wallpaper with a modern, sleek design, inspired by the style of Windows 11 wallpapers. The main 3D form should have smooth, flowing curves with a dynamic, organic shape, and should be rendered with a dark, metallic finish. The form should primarily be in dark shades of gray, giving it a sophisticated and industrial look, while leaving ample negative space to create a balanced composition. Add subtle, vivid green accents (#00C061) to the metallic surface, strategically highlighting the edges and curves to add a touch of contrast and vibrancy against the dark gray tones. The green accents should reflect light, emphasizing the form's contours and adding depth to the image. The background should feature a soft, light gray gradient, transitioning smoothly from a lighter to a slightly darker shade, enhancing the metallic sheen and creating a strong contrast with the dark form. The 3D form should be positioned slightly off
