Very cool looking. I love how the lines slice it like graph paper.
It sort of looks like a beautiful, colorful air balloon rising high in a blue sky. I like how the colors are all rainbow, transcending from one to another as the sphere curls, going into itself, almost like a tunnel effect. It's interesting how it plays with the eyes, making it a bit tricky, as you try to figure out what part is going in, or coming out, etc.
