Design a glowing, holographic blueprint of a strange device or structure

Design a glowing, holographic blueprint of a strange device or structure, with complex and unfamiliar schematics. The blueprint should be projected in mid-air, with rotating elements and detailed, alien designs. The colors should be cool and luminous, like neon blue and green, with an otherworldly feel. The background could be a high-tech workshop or a shadowy, hidden lair.
