A Colorful Spider

This colorful spider was found on the camelia bush beside our carport.

The thing that initially caught my attention was this ball hanging over the spider. It appears to be a part of the web complex, and looks like some kind of egg sac, but I have never seen one like it before.

This view showed more of the back pattern of the spider.

The under side of the spider shows his web spinor and you can see one of his eight eyes.
