Aaron Tang's wall stairs are meant for living areas that are short on space, but they're so awesome that I'd want them even if I had 1,000,000 sq. ft. house.

When finished, the stair frame slides back in the wall and the planks stand straight up, flush against the wall. Imagine, next time you're at a mansion/estate/castle party, you walk into the foyer to find no stairs at all. Then the owner hits a button on a remote and stairs appear from the wall. I'm pretty sure your mind would be blown. [Aaron Tang via Architechnophilia via TreeHugger]
