Laser-Engraved Optical Crystal Cube of Canis Major

Full prompt

A horizontal 3:2 desktop wallpaper composition presents a precision macro photograph of a solid optical borosilicate glass cube resting on the left side of a textured matte black volcanic basalt slab. Inside the transparent glass, a three-dimensional sub-surface laser engraving renders Canis Major with pristine astronomical accuracy. Sirius radiates as an intensely brilliant, multifaceted refractive node, while Murzim, Wezen, and Adhara form the hound's anatomy with tiny micro-fracture points catching cool white studio illumination. Delicate caustic light reflections and prismatic chromatic dispersions sweep across the volcanic stone surface toward the right, leaving generous, clean negative space across the dark textured plane. The minimalist setup highlights optical clarity and structural laser craftsmanship.
