A spinning wheel of "cards"

I would like to add a view to my application where I basically have a revolving circle of "maps" (rounded rectangles and information in them) that the user can swipe in. To get the illusion of cards laid out on the wheel, they will obviously need to hide from the screen at a slight angle.

I was just looking for some guidance on how I would go about doing this. I thought I would start with a UIScrollView where the cards slide horizontally and then work on the corner later? They'll probably also need an animation that centers them in the view as they slow down to a stop.

Do you have any tutorials for this kind of thing? I did some searching and I couldn't find anything.

Here's what I'm looking for:

Thank.
