This artwork started out as an ordinary piece of clip art.
There are three different types of Flash animtions here.
The pupils of the eyes are moving using Flash's motion tweening.
A motion tween allows you to place an object in one position
on one frame and another position on an second. Then Flash
fills in the in between elements by itself.
The fingers are moving using Flash's Shape tweening. The
is also called "morphing." With morphing Flash
fills in the differences between the shape of an object.
So in this
case I simply drew the each finger in an up or down state
and let Flash fill in the between looks.
The blink of the eye is tricky. I thought I'd have to do
a Shape tween between the eyelid in the up state and the
down
state. But what I discovered is that all I needed was the
eyelid off in one frame and one in another. I didn't need
any tweening
at all. The blink happens so quickly that you would swear
that the eyelid moves down. But it doesn't. Your eye fills
in the
rest.
