The Screening Siphon appears as a twisted amalgamation of vintage film projector components fused with supernatural energy, constantly shifting between different horror movie visual filters as it processes experiences from each venue. It emits authentic film grain and VHS static that permeates the air around it, while ghostly movie scenes flicker and dance in the ambient space, creating an otherworldly screening room wherever it manifests. The device produces the mechanical clicking sounds of film reels combined with ethereal whispers of classic B-movie dialogue, and its lens glows with an ominous light that seems to peer directly into the souls of Horror Hall of Fame participants.

The Screening Siphon maintains narrative continuity across the entire grindhouse series by absorbing the most authentic horror moments from each league venue and projecting them as supernatural atmosphere at others, ensuring that every player's archetype journey feels connected to the greater B-movie nightmare. It serves as the mystical infrastructure that enables Horror Hall of Fame archetypes to carry their cinematic power between different horror subgenres and venues.
