Spiral staircase

@Cathie et Michel: As Ines guessed, it is a spiral staircase that has been confused by the strong shadow cast. I was interested in getting a more abstract design in the image. Thanks for stopping by.

@Inés: Yes, you've got it, Inés. As I mentioned above I emphasized the shadows which obscured the shape of the stairs for the sake of a more abstract approach. Thanks again for stopping by.
