I played with Sencha Touch and wrote a touch based memory like game.
For me as Ext JS developer it was pretty easy to write that application.
This cause Sencha Touch has the same syntax like Ext JS.

My first application a memory like browser game run on iPhone, iPad and Android.
It use the “tap” event and flip the cards after the tap with one of the nice animations.
