A striking 3D render of a complex spiky polyhedral shape, illuminated with contrasting warm orange and cool blue lights on a dark background.

Create a detailed, three-dimensional polyhedral shape with a harmonious design based on the Golden Ratio. The shape features inward indentations and outward spikes positioned according to the φ (phi) ratio, with proportions and spacing following Fibonacci sequence principles. The surface is smooth with elegant curves, and the structure embodies balance, symmetry, and sacred geometry. Include subtle shading and lighting to emphasize depth and the intricate connections between inward and outward points, evoking a sense of cosmic harmony and energetic flow. See more
