Applications of category theory are described by Julie Rehmeyer in ScienceNews under the banner

One of the most abstract fields in math finds application in the ‘real’ world.

Now, how about applications in the real world?

Going to the extreme, does anyone know of examples for which some of the simplest category theory concepts (perhaps in the form of diagrams) could be used as a teaching tool to elucidate some fundamental mathematical principles (for example, the distributive property) that are typically taught in secondary school? Then perhaps one could use those examples as a wedge to more easily introduce concepts of a less elementary nature. Students would then have a chance to become aware of category theory and even start to use it as a tool of their own. Now that could lead to big changes.
