unfolding surprises

Here are two videos of some surprising unfoldings.

The first is from New Scientist, posted as part of this article. This shows some unfoldings of a polyhedron with a large number of sides (enough sides so that the polyhedron resembles a sphere).

The second (which may fail to show up in your reader) is from Erik Demain's site. This shows several unfoldings (and refoldings) of a cube.
