Create an image of a sculpture that visually represents the emotion of joy. The sculpture should be crafted from sunlight, conveying a sense of warmth and radiance. It should consist of swirling, fluid forms that rise upwards, with hues of gold, bright yellow, and soft orange intermingling to create an aura of happiness and light. The sculpture should seem to be almost alive with movement, embodying the uplifting and energizing quality of joy. The background should be simple and elegant to ensure that the sculpture stands out as the centerpiece. The sculpture itself should be on a modest pedestal to give it a sense of importance without detracting from the ethereal quality of the sculpture.
