Vertical video blue neon question marks particles loop animation

This animated vertical background features an endless cascade of glowing blue neon question marks. The symbols fall gently downwards at varying speeds and sizes, fading in and out as they move across a deep blue background. The clean, crisp outlines of the question marks create a digital and mysterious aesthetic, making it an ideal visual asset for projects requiring a sense of inquiry, thought, or conceptual exploration. Perfect for social media stories, educational content, quiz videos, presentations, or any vertical video format that needs a dynamic and engaging background to represent questions, curiosity, or problem-solving.
