Neon Cavern Beneath the Redwood Forest

In a redwood forest, a massive cave mouth opens to a bioluminescent cavern where nature and high tech collide: stalactites glow with embedded circuitry, fiber-optic vines, and holographic signage flicker in cyan and magenta along damp mineral walls. A shallow stream winds across slick rock, reflecting neon light. Bioluminescent mushrooms, moss, and sprawling redwood roots descend like cables into the chamber. Outside, colossal redwoods loom through mist; rain-dappled leaves frame the entrance. The scene is cyberpunk-futuristic, moody and cinematic, with high detail, dramatic lighting, and a sense of otherworldly fusion between forest and machine.
