This animated background features an endless tunnel created by an array of vibrant, glowing geometric cubes. The cubes, rendered in bright, neon-like colors such as pink, blue, green, and yellow, radiate with a soft luminescence against a deep black backdrop. They dynamically expand and contract, moving outward from the center like a pulsating vortex, creating an immersive and rhythmic visual flow. Ideal for adding a futuristic or abstract touch to various projects, this seamless loop can serve as an engaging backdrop for VJ visuals, concert stages, event projections, or digital art installations. Its continuous motion and colorful glow enhance any scene with a dynamic and energetic presence, making it perfect for creative compositions requiring a captivating visual texture.
