I've been working on close stringers for curved stair cases.  The circular variety is pretty much figured out but the elliptical variety still needs an instantaneous adjustment to the stringer depth since the pitch angle of the stairs (slope) is constantly changing.  The geometry of a 0.9 eccentric ellipse shows off this distortion quite well.  I will hit it again tomorrow and see if I can't figure out a more accurate algorithm for these stringers.  Sometimes I enjoy a good challenge, but this one has certainly had me scratching my head a few times already.
