Write an iPhone application

I need a very simple, portable solution constructed using regular UIViews in XCode for simulating turning over a playing card. The requirements are as follows: * I should be able to load my own view into the view composing the "back" of the playing cards. * I should be able to load my own view into the view composing the "front" of the playing card being flipped. * The playing card should respond to touch events in such a way that the card flip tracks or "attaches" to the user's finger/drag gesture so that it "feels" as if the card is sticky and a physical object. * Once the flip has reached a certain point where the face has been revealed, it should complete the flip by "detaching" from the touch and "falling" onto the rest of the simulated stack. Note that, while I use terms like "falling", this is to be done with UIViews and not within a physics engine. So these things must be simulated within standard code. I'm looking for a nice approximation so that this is a very tactile process but not a 1-to-1 physical simulation. I am attaching sample animations. You'll see that the first two animations (down and across) don't feel very natural. But the diagonal animation has a more natural feel. This is what I'm going for. This feeling is the critical requirement of the project. Without it, the project is not what I need. Please let me know if you have any other questions! So that I know you've read the requirements, please indicate you have with the words "Ace of Spades". I want to know you're personable and take the project seriously. Thanks!
