I've used radial for iris's before.  It works pretty well but is too regular.
I've tried adding turbulence, but it moves the center too much.  Maybe f_noise3d
would work better... hmmm

I agree with the look_at vector.  Probably one of the reorient macros would
work.  Hmmm... and have it react to brightness, too?  So the size of the pupil
is smaller for brighter light.  And IIRC, the pupil changes size with the
distance of whatever you're looking at.  I'm not sure how, though.  You could
use the distance to the look_at vector to calculate that.

Well... now I'm gonna have to go and do some research. :-)
