Develop a Facebook ad post (1200x628px) featuring a 3D-rendered futuristic art gallery that showcases digital artworks created with AI. Use neon light beams to highlight the artworks, creating a dynamic visual experience. The background should be a purple-to-blue gradient, enhancing the futuristic atmosphere. At the top, place the headline: 'Learn AI Art & Earn from Creativity!' in bold, sleek typography that contrasts well against the background for maximum readability. At the bottom, add a glowing CTA button: 'Get Started Now', ensuring it stands out as a focal point. Incorporate elements like glowing paintbrushes and digital brushes turning into dollar signs to symbolize the earning potential of the course. The overall design should be clean, professional, and visually engaging, capturing the essence of creativity and innovation in AI art.
