I want to write a simple app for mobile devices. At startup, the app presents a page with a few, simple choices (say three buttons). After the user selects her choice, the screen goes black for some amount of time. After the timeout, the user is again presented with the choice screen, and the process repeats. Suggestions on how to get this behavior? Is there a particular Sencha Touch example that would help me figure this out.

Thanks in advance!
