| 1. An apparatus, comprising:
a unitary blank of a substantially planar sheet material including a plurality of panel portions interdivided by one or more
bending line portions, wherein said unitary blank folds along said one or more bending line portions to produce a three-dimensional
structure that supports a portable electronic device on at least one said panel portion over a surface at an angle inclined
relative to said surface; and
a fastening subsystem, coupled to said unitary blank, having a holding mode for maintaining said unitary blank folded in said
three-dimensional structure and a release mode for transitioning said three-dimensional structure to a planar structure, said
fastening subsystem providing for repeatable transitions between said holding mode and said release mode.
