One Zipper Unfoldings of Polyhedra

From Make.

Just discovered this fascinating little geometrical recreation at the 2011 Bridges Math Art Conference galleries. The idea is simple, and the field still fairly unexplored, from what I can tell. What interesting 3D shapes can be made by zipping up the edges of a planar shape using a single zipper?

A bit of Googling brought me to the homepage of Macarthur fellow Erik D. Demaine, whose work in origami and other geometrical fields we have featured here many times before. You can click on his name at the bottom of this post to see our aggregated past coverage of Erik’s work.

Pretty great stuff.
