I could see building an operator that used an embedded fcurve to
drive bone rotation working without too much difficulty. Although you can’t
animate the shape of the fcurve so you may find it limiting. Another approach
might be to use a standard spline curve and use it’s height/U mapped into bone
rotation. Could be fun.

Subject: Organic unfurling or unfolding animation
I am trying to animate the way a flower or plant might
unfurl or open. I have been messing around with chains, curves and lattices. I
can get some interesting results with each approach, I just can't get it to do
exactly what I'm looking for. I would like it to unroll from it's spiral shape.
Using expressions on bones seems like a good way to do this. What I would like
is a curve to edit the shape of the spiral. Is there a way to get a profile
curve similar to the Proportional Modeling box? I would like to have the curve
drive how much to multiply the first bones rotation value. The motion I like is
similar to the "wrench" flower in the Sears Arboretum spot.
Am I making any sense?
