Here's what I did with it. It took about 20 minutes in Photoshop with a mouse (a graphics tablet would be easier and quicker). Used the spherize filter to enhance the sphere and then just used the eraser, blur tool, clone stamp and smudge tool to clean up around the outside of the sphere. Also added a drop shadow to the ring that comes across the front of the sphere just to give a bit more depth to it. The lower left section of the sphere could use a bit more work but it's good enough for this example. Matt.
