an tropical octopus in a reef, mesmerizing fractal structure made of inspired by the Mandelbrot set, glowing with intricate beams of iridescent light. The fractal evolves endlessly, with layers of neon blue, violet, and gold cascading into infinity. Delicate sparks of pure white light trace each edge, creating an ethereal and dynamic effect. The background is a cosmic void of subtle, dark gradients, emphasizing the brilliance of the fractal. Positive: fractal symmetry, glowing light, iridescent colors, dynamic flow, ultra-detail, cosmic void Negative: flat shapes, muted colors, blur, noise, chaotic composition
