The Eyes Have It!

Looking at creating the eyes for the sunflower, I have tried a couple attempts at doing deformers. But when the Iris rotates, the deformer makes the iris deform as well.  What I wanted to do is create an eye that has a non-round shape, but has the pupil and iris keep a round shape.  I went with a projected texture and normal map.  I think it will work splendidly.

This is the deformer eye rig.
