Excerpts: The controlled folding and unfolding of maps, space structures, wings,
leaves, petals, and other foldable laminae is potentially complicated by the
independence of individual folds; as their number increases, there is a
combinatorial explosion in the number of folded possibilities. (...)

Our observations and analysis provide a mechanism for naturally occurring
Miura-ori. Stresses induced by the relative growth of stiff skins on soft
supports will spontaneously fold into structures (...); stress-mediated
apoptosis may then separate the skin from the tissue to form deployable laminae
such as leaves and insect wings.
