Spiralling what?

Well this one is not too hard to identify, isn't it? Hint: it's not a snail shell. So it must be a staircase.
Still I like the strong geometry and the almost monochrome colors, which btw. were tweaked here to get a little more dynamic in the violet and the green on the right - which I like as a contrast to the black, grey and white of the staircase. Enjoy!
