Would allow for slit pupils, vertical (e.g. cat, fox) and horizontal (e.g. ferret).

Actually on second thought, this would be better tied to keyframes in the application itself, so that pupils can be dilated (i.e. slit pupils become rounder) as the character gets more excited.

I think custom shapes would be better for odd pupil shapes like goats.

I agree that it would be cool to change pupil/iris size in scenes.

Yeah just like that.  Man I wish I had some time to play with this thing.  I mean the app.
