Interactive Clothing

I found this T-shirt online. I could not find who it was by but I did find a website where they give you step by step instructions on how to make one. It is a T-shirt with a car track on it designed so that an adult can lie down and the children can play cars on the back. 

This is designed to be fun for the kids and give a massage for the adult. This is a simple yet great example of clothing designed for children to interact with.
