A glowing hourglass with colorful sand and sparks.

In the heart of a dark, enigmatic space, an hourglass stands as a mesmerizing focal point, its glass body glowing with an ethereal, otherworldly light. The hourglass, crafted from dark, polished wood, exudes an air of timeless elegance, its slender neck and bulbous bulbs creating a striking silhouette against the void. The upper bulb is filled with a vibrant, cosmic mixture of pink, purple, and blue hues, as if the sands within are composed of stardust and nebulae, hinting at the vastness of the universe. The lower bulb, in contrast, is filled with a fiery orange sand, glowing with an inner warmth that contrasts beautifully with the cool tones above. The sands flow slowly, creating a dynamic interplay of light and shadow, as if time itself is being measured in the most fantastical of ways. The hourglass rests on a dark, textured surface, which reflects the glowing sands, adding depth and dimension to the scene. The overall atmosphere is one of mystery and wonder, inviting the viewer to ponder the passage of time in a realm where the boundaries of reality seem to blur.
