Unfolding linked layers?

Here's a year old tutorial teaser that Andrew Kramer never completed.

Would there be a script or expression that would accomplish this? Linking a user-defined edge of "x" number of layers to rotate around that edge while controlling visibility? (and perhaps following a path?)

I know it can be done with parenting and opacity expressions and anchor point repositioning, but just wondering if there as an automated to accomplish this.

yes...please let us know if you have any other ways of doing this ;)

I've built that animation using expressions.
The attached project file includes 3 versions of the effect (each of them fully customizeable):
1. Straight path
2. Circular path
3. User defined path (Motion Path)

Use the "Controller" layer sliders in each composition to change the parameters of the animation.
The "Straight" and "Circular" are fully automatic. The "Motion Path" animation needs tweaking of a spacing parameter to make it perfect, according to your path.

1. Straight:
rotation axis - chooses folding direction: front or left
T - speed of animation (duration time for each fold)

2. Circular:
N - number of elements in the circle (the radius of the circle will be calculated automatically, based on the width of the element)
XY_Center / Z_Center - center of the circle
T - speed of animation (duration time for each fold)

3. Motion Path:
(*) You can change the path of elements by changing the motion path of the "Path" layer
(*) Use "roving keyframes" for the position keyframes of the "Path" layer !!
(*) The first and last "Object" layers have slightly different expressions,
so if you need more elements just duplicate one "Object" layer from the middle (not the first or last layers).
N - number of elements. Don't forget to change that according to the number of elements (object layers) you have !
dT - Chooses the distance between the elements. Change that value until you have them all aligned perfectly in the FRONT view.
T - speed of animation (duration time for each fold)

Let me know what you think.

p.s.: Thanks to Andrew Kramer for the idea !
