I thought I would share this here on the forum. One of my students had a question about other methods of creating ears, in this case using splines. The trick with this is to quickly layout the ears in 2D then smooth shifting to get the mythical “3rd” dimension. 
Heres another way to do it with splines:
In fig 1. I simply lay out the splines to follow the contours of the ears and also divide it into 3 zones.
Once the splines are laid out I make sure the inner most splines are divided into a 4 sided patch (orange arrows).
In Fig 2 I then add splines that will make sure the whole thing is divided up into 4 sided patches. The innermost 4 splines will determine where the other splines (orange arrows) radiate from
In Fig 3 I use the patch command to create polys inside each spline patch.
In Fig 4 I do a little detailing and spin quads to tweak it.
As you can see I smooth shift Zones 2 and 3 in and then smooth shift zone 3 in further.
The time on this is about 10 minutes
Im also including a ZIP file with the LW object with each stage in different layers for you to look at.
