A Halloween sign reading "TRICK OR TREAT" in a scary, dark blackletter style. Black stacked letters with white outlines and dripping blood hang on a weathered wooden board over a porch with glowing jack-o'-lanterns, cobwebs and lit lanterns. Remake it with your own text, swapping the greeting, house name or address on the board.

Thick crimson blood saturating every surface — viscous, high-density fluid with authentic physical behavior: large tear-shaped drops suspended at each drip terminus with surface tension visible at the meniscus, connecting streams thinning as they extend downward, deep near-black pooling where blood accumulates. Material properties: subsurface scattering gives deep red glow when backlit, specular gloss on convex drip surfaces catching directional light, matte-dark at clotted pooling zones. Blood color gradient from bright arterial red (#CC0000) at active drip streams to near-black clot (#3D0000) at base pools. Gravity-driven physics — every drip pulled downward with anatomically accurate tension. Horror film practical effects quality — not painted, not stylized, photorealistic blood. A decorated Halloween haunted house entrance at night — ornate Victorian porch, carved pumpkins lining the steps with warm candlelight glow, cobwebs draped from the eaves, flickering lanterns on both sides. Above the front door: "TRICK OR TREAT" carved into a dark wooden sign in gothic blackletter with blood seeping from the carved grooves, rim light catching the letter edges against the dark wood. Warm inviting yet terrifying Halloween house energy. The sign looks handcrafted and genuinely old.
