iPhone App Design /// Opened Menu

Hello to anyone,

As a ixd designer, I like innovations. When I designed this app, I tried to give it some specifics. Because the app is composed of modules, I decided not to display menu, and display it in the case when the user wants. So, user can open menu anytime anywhere on the screen by DOUBLE TAP. Menu will slide down from the top.

It is like in iPhone, when you want to see what apps are running. I think this idea can live.

What do you think?
