Gradient glassmorphism 3D icon set (cutout)

This image features a collection of twelve distinct 3D icons displayed in a grid on a dark navy background. Each icon is crafted in a trendy 'glassmorphism' style, characterized by a semi-transparent, frosted material with subtle neon-like edges, blending soft cyan and vibrant violet gradients. The icons depict various abstract movements, physics concepts, or UI functions: spheres, cubes, stacked objects, and directional arrows. The lighting is soft and internal, creating an ethereal, glowing effect that suggests high-end digital interface design. The layout is clean and symmetrical, with each icon perfectly centered in its quadrant, emphasizing a minimalist yet futuristic aesthetic. The overall quality is crisp, likely rendered in 3D software like Blender or Cinema 4D, making it suitable for modern web application dashboards or creative design projects requiring fluid, dynamic visual elements.
