Finally decided to try one of the GSG 5sec projects. I used this as an excuse to learn more about rigging and creating folding paper. I learned quite a lot and was able to tackle a fairly difficult effect: unfolding a z-fold of paper (like an accordion). Messed with a couple different ideas, and finally found a good solution: Unfold using bones, then use a spline wrap with dynamics on.
You can see the process and discussion here (with project files):
