Build an app, for demo purposes, that does nothing more than showcase each component / widget. Demonstrating its [each component] usage potential and built in [templated] styling variations.
The people who designed the components will have had usage scenarios in mind .... show them to us. The app would not be a real world app i.e. it does not have to be an example of a "real" app ... just how the components can look and be applied. We can then copy the example look and feel... this helps if we are not natural UI designers
