Stairs, stairs and more stairs

It seems that I'm only able to build stairs. Since I knew that Select Artists were allowed to participate in the Marine Theme Week, and I saw the great stuff that was going to be published, it came to my mind that a folding staircase could be nice for lighthouses or those lots that resembles a boat. So I googled "folding stairs" and found images of how they looked like. It took me a while to mesh them, and there's no way that I can make the animations working (that would need a much smarted artist than I am), but I think that they turned out well in the end. They will be published tomorrow, with some wooden and some metal recolours; please, let me know what you think about them.
