Packaging Egg Box - No, it isn't software exactly. But it is a great example of a design that works well at revealing the beauty and nature of the content to the user rather than hiding it, which is what UX design ought to do more.
Cowboy Kitchen - Like a big hutch when it's closed and then an awesome table with storage when it's opened! (Except the price.) This matches my furniture and would be great in the dining room for an extra table and seating.
