Un cartel de Halloween con el texto "TRICK OR TREAT" en un estilo blackletter oscuro y aterrador. Las letras negras apiladas, con contorno blanco y sangre goteando, cuelgan de una tabla de madera envejecida sobre un porche con calabazas iluminadas, telarañas y faroles encendidos. Rehazlo con tu propio texto, cambiando el saludo, el nombre de la casa o la dirección del cartel.

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.
