Idea(s) in how to demonstrate the project

Just been thinking in how to get across the functionality of the projects interface, the best way for me would be to use both user interaction and animation footage, to explain what I mean by this, the project will be delivered using director, the problem I have had is the time it take to code the backend in the time frame I have.
In having the combination of functional and non-linear animation, the user can get a feel of using the interface without the need for complicated code, just area detection and go the frame codes.
