Question what is the fastest & best way to animate ear bone rotation ? (pic)

Hi!
.I am looking for a way to "automate" the ears of this giraffe with rotation only
so that when the head moves the ears react to that..
I have been looking for a simple solution for long ..now I have to find a solution
or if there is none..to animate manually more then 3500 keyframes..
since Im using a cat rig the scripts I have tried dont work..
any idea to try would be welcome!
thank you
Elad

Would the flex modifier be appropriate?

Can you create a few morphs for the ears, then link that morph to head bone movement via script?

Have you looked in to using spring controllers at all? I've gotten some decent automated secondary animation with them in the past. They're history dependent though, so by the end of 3500 frames of animation they'll probably chug pretty bad. If you want to make any changes to the animation though you can just turn them off and back on again when you're ready to render.

well do you want procedural animation or scripted?

Thank you guys for your suggestions,

Anthonyy, I have tried the flex modifier..but it is very limited in the way it creats the animation and very hard to control and avoid the ear being thrown away into and far from the model..( in faster animation parts)

floatingworld, Im looking for something closer to procedural animation then scripted
because I have no knowledge in scripting, so I cant try the morph solution you suggested..though it sounds good.
and I wish there is a simple way it can be done.. since basicly the head bone
and the ear are just two simple boxes. and when the first move..the other needs
to react to it from its pivot, while keeping the general shape..

Pacermike, spring controllers where my seconed thing to try after flex..and the problem was that the ear is moving on the rotation axis ..and the spring controllers move only on the moving axis..so I cant seem to use them for this purpose..(when I try to add spring
to rotation in the assign controller menu..it doesnt exist there..)

Flex can work quite well if you know how to use it.

But if you would rather use springs, the way to have them drive rotation is to place a point helper out by the tip of the ear with a spring controler on it. Then make a bone with its pivot where you want the pivot to be, and then use a lookat constraint to tie the bones rotation to the position of the spring helper. This will cause it to rotate like you wish.

Hope these help
