Imagine a serene landscape where floating cubes of various sizes gently hover amidst a twilight sky. Each cube emits a soft, pulsating glow in shades of blue and violet, casting delicate reflections on a tranquil lake below. Surrounding the scene are wisps of mist that dance in the cool breeze, while distant mountains loom under a star-studded canopy, creating a harmonious blend of light and tranquility.
