A sculptural book exploring the relationship between humans and parasites through the metaphor of screws. Inspired by designers like Piet Zwart, its rigid, mechanical visual language reflects societal parasitic dynamics and fears of unseen forces that infiltrate and exploit our systems. Laser-cut from scrap wood, stained, and screw-bound, the book can only be accessed by unscrewing the cover, making its physical construction an extension of the concept.
