Envision a surreal landscape with a GNU standing on a rocky outcropping, gazing out at a vast, starry night sky, with wispy clouds and a crescent moon, and a subtle glow emanating from the GNU's body.

Design a whimsical illustration of a GNU character holding a paintbrush, surrounded by a swirling vortex of colors and shapes, with bold brushstrokes and textures to give a sense of energy and creativity.

Create a futuristic cityscape at sunset with a giant GNU logo hovering above the skyscrapers, surrounded by vibrant colors and neon lights, with a subtle gradient effect to give a sense of depth and dimensionality.
