Do you think it is possible to create a VFP user control based on your classes? For example, one that called Mini Apps Tray on Android tablets -- a horizontally positioned tray with app shortcuts (icons) with smooth scrolling left and right.

My idea that some kind of practical application of your classes is required. One that can easily be understood by the public (and I am one of them). I bet any VFP developer agrees that the demo looks cool. But the obvious learning curve cannot be justified by coolness only. You need to show something practical, a bit down to earth. You need to answer a VFP developer's question: "How this can benefit my VFP accounting (or HR, or CRM) application?"

It is also advisable to keep English-based UI in your demos. For example, a Cyrillic menu in your demo may scare user off from clicking on it just because the user has no idea what would follow a click.

Evidently you have spent plenty of hours on the development. And the result does look impressive. IMHO, now it's time to shift the focus on promoting it.
