From one of the sessions I attended I learned about a website called Blabberize.com. My second oldest daughter used it to do her science project. When making the mouth, the large green dot indicates how low the mouth will drop. It was hilarious fun to make. Enjoy the production.
Update: If we would have watched this video tutorial, it would have been even easier to make our first 'Blabber.' Exploring is nice, but trial and error can be time consuming. I also discovered an example of how this Web2.0 tool can be using in the mathematics classroom.
I wonder if this blabberizing animals can be considered an application of Genesis 1:28 - having dominion of living things that move on the earth.
