In Kim's comment to "What do you see?", she posed a question from Matt. The answer to this question is almost giving away what I see, but I think it is only fair for those viewing the blog and not attending the Celebration to know the answer first.
Matt's question: Would a water bottle be a "water bottle" if it didn't have water in it?
I hope these images will help to explain my answer.
Kevin's answer: A container is designed for a purpose, the contents of that container do not change its purpose. A container is not defined by its surroundings, capacity or fullness. Said more clearly, a container is defined by its creator.
Do you see what I see about the water bottle now?
