All sorts of family related chores to do today but I have managed to squeeze in a bit of work on the bird project. I was trying to change the way the head moves to give it a little twist as it moved up and down. The head is joined to the body using a four bar linkage. Keep the opposite pairs of linkages in a four bar linkage parallel and all the parts move in a regimented lined up fashion. Small changes to the alignment, however, can make for more fluid looking results. Check out the animation above. In the bird on the left horizontal bars are 50mm long and the vertical bars are 30mm. The result is a straight forward parallel movement. In the bird on the right the vertical bar joining to the head is only 25mm long, all other measurements are the same. The result gives the movement just a little kick and a little more realism. I've implemented that new linkage set in card and it works nicely. Pics tomorrow.

Yes, I prefer the improved version on the right. It looks like a more natural movement.

If ever you run low on ideas... Like that will ever happen.
But seriously, you have written many good tutorials, I was thinking that you could do a tutorial on how you created this animation. I love the subtle way you show the head changing from a rigid move to a smooth and natural move.

I created the animation in Flash. Rather than going back and writing a tutorial on that animation, how about I write one for the next animation I create?

That sounds god to me. Thanks!
