The above photo shows a card made by my friend, Jaimie. She is also the greatly-mentioned-in-this-blog Stampin' Up! demonstrator that I know. From this card, I came up with the following cards.
My hand is in the photo here to hold the card flat. Otheriwse it would tip over because of the unique front "cover" of the card. (It is smaller than the back of the card... made by cutting off most of the original base and replacing it with a matted/layered piece.)
Here is another version of the same idea... but the flap of the card opens up (as you can see).
