Hi all.

I'm experimenting with a CSG model of an alien creature (still mostly
unfinished), and finally figured out a nice way of making eyelids that
flow properly around eye holes of various shapes, so I decided to play
around with different expressions that can be made using only the
creature's single eye:

http://eusebeia.dyndns.org/pov/tutki/test01.html

The different expressions are all fully specified by a set of 6
parameters to the eye macros I made. No after-the-fact
hand-tweaking was done, because I want to eventually use the model
in an animation, and hand-tweaking every frame is not practical.

Comments? :-)

Yes, definitely expressive.  I'll be interested in updates.  I do always
appreciate SDL-only animation & characters too.

Thats really an eyemouth. Much of the expression attributable to the 
variations in the lower lid are lip cues. Clever.

Not very expressive in that so many are the same. If one squints, they all
look alike.  If it's the main source of emotion, you gotta make it much
bigger, or make the effect be the main thing a disinterested party would
get if they made a quick sketch of your frame.  Maybe consider animating
the pupil size, iris color, bend of the eyestalk, goose bumps or "hunches
of skin" along eyestalk, cartoon elements like smoke, sunbeams from eye,
etc.

You're right, as a whole the model isn't very expressive yet. But I was
mainly concerned with the eye, since that is the part that I have worked
out in detail (and even then, I still haven't added eyeball rotation for
looking around yet). The rest of the model is incomplete, and is just
there as a crude sketch of what it might look like in the end. I will
eventually add a mouth as well, which should add to its expressiveness.
