The gradient is amazing. It makes the fractal have a life I didn't find in other fractals. The different gradient, dark, blue/pinkish, gives the fractal a depth that I really like. But the sharpness of it all is really what gets to me. The half dark hole in the central left and the glass wall in the right it really makes all the central piece comes alive. And all the details mattering. The more I look, the more I like.
