No - there are no steps - they are flat paths laid out in rectangles that are offset giving it a 'stair step' look. I saw them and thought I uploaded a photo but it doesn't seem to be here now. The google link is so you can see the shapes that are flat on the ground. You can imagine using dominoes to mark the diagonals of rectangle while keeping the sides of the dominoes parallel to the sides of that rectangle.
