Northern Lights

A dynamic aurora-like shader effect dominated by luminous, flowing waves of green and purple light against a deep dark-blue to black background. The primary visual element is a large, glowing green mass in the center-right portion of the image with soft, diffused edges that fade into the dark background. Overlaying this green glow is a distinctive purple-to-cyan gradient arc that curves across the upper portion, creating a ribbon-like aurora effect with high luminosity and a subtle waviness. The green light exhibits a bright, almost neon quality with significant glow and bloom, while the purple arc maintains a more ethereal, translucent appearance. The entire composition has a soft, out-of-focus quality with gentle gradients and no hard edges, creating an atmospheric, otherworldly mood. A subtle film grain texture is applied across the entire surface, adding a slight noise pattern that enhances the organic, natural feel. The lighting appears to emanate from within the green mass, with the purple arc acting as a secondary light source creating depth and dimensionality. The overall effect suggests a bioluminescent or celestial phenomenon with smooth, undulating motion captured in a single frame.
