Interfaces of Fruits

Have you ever thought of the interfaces of fruits?

I saw a very interesting post by a group of students at Birmingham University.

Yes, we always relate interfaces with computers or domestic appliances, never made a relationship with fruits! However, fruits do interact with us by their unique interfaces. And this topic actually can be expanded to lots of objects almost infinitely.

What about vegetable interfaces then? Which one gives you the best exprerience of getting entrance to their internal edible interface and consuming that? Which one is the worst?
