Evolution of the Breast

While working in Arizona last week, my mom and I went to the Botanical gardens. There was a glass show that was really fascinating. Here are a few pictures of some of our favorites...

and then there was this one... I named it "Evolution of the Breast" and it seemed fit as people were walking by saying "and what does that look like, honey?" Why did he choose that peachy color? Why is there a little tip? Why do they start out pointing high in the sky and as they progress they elongate south? Coincidence? I don't think so! But entertaining all the same....
