Fractal Fibonacci Spiraling Nautilus Seed Gallery

Begin by plotting the Fibonacci sequence onto a sheet of marine-grade plywood, marking the golden rectangles to define the sweeping curvature of the outer shell. Use a high-precision jigsaw to cut these interlocking segments, ensuring the edges are sanded smooth for a seamless flow.

Construct the interior spiral ramp using thin, flexible strips of cedar that are steam-bent to match the nautilus chamber radius. This internal pathway acts as a gravity-fed slide, gradually depositing sunflower seeds into the central feeding basin at the base.

Assemble the outer facade using vertical hardwood slats attached to the plywood skeleton, creating a ribbed texture reminiscent of an ancient fossil. Each slat is spaced precisely to allow birds to perch while protecting the seed cache from direct rain and wind exposure.

Apply a natural, food-safe tung oil finish to highlight the grain and provide weather resistance for outdoor longevity. Mount the structure using a hidden pivot point at the center of gravity, allowing it to gently sway with the breeze like a rotating shell.
