This reminds of I conversation I had with a mobile developer. He came up with a prototype to show to a client. The prototype was just interactive screenshots with nothing going on in the backend. After showing it to the client, the client was excited that the app was pretty much done. The developer explained that this was just a prototype and all the coding still needed to be done. The client couldn't understand and kept saying that it was basically done.
