Bioluminescent Celestial Constellation Seed Map

Begin by milling a dense piece of dark walnut to serve as the dark sky backdrop. Carefully mark the positions of major constellations like Orion or the Big Dipper based on an astronomical chart.

Use a CNC or high-precision drill press to create apertures at each star location, sizing them specifically for different seed varieties. These holes allow birds to access the interior chamber while mapping the cosmos.

Apply a non-toxic, weather-resistant glow-in-the-dark pigment epoxy into the etched constellation lines and larger star drill-points. This provides a subtle nocturnal luminescence that mimics the night sky after the wood has been sealed.

Construct a clear acrylic hopper behind the walnut face to hold birdseed, allowing the stars to remain visible as levels fluctuate. Mount the assembly within a minimalist floating cedar frame for an elegant, modern display.
