Floating Glass 2

A luminous, organic shader effect featuring a glowing lime-green to yellow-green gradient that radiates from a central focal point against a deep black background. The effect creates a smooth, flowing tunnel or vortex-like structure with soft, diffused edges that fade into darkness. The primary glow exhibits a bright, neon-like quality with highlights of near-white (#feffe3) at the brightest points, transitioning through vibrant lime-green (#a1eb31) in the mid-tones, and darkening to deep navy-purple (#1a1c38) in the shadows. The shape appears to be a ring or toroidal form with a glass-like refractive quality, creating subtle light bending and fresnel highlights along the edges. A fine dithering pattern with blue noise is subtly visible across the surface, adding texture and preventing banding. The overall atmosphere is ethereal and otherworldly, with a sense of depth created by the gradient falloff and the glass refraction effect. The lighting angle appears to come from the upper left, creating dimensional highlights and a three-dimensional appearance despite the abstract nature of the form.
