Inspiration from: Ernest Irving Freese's "Geometric Transformations": The Man, The Manuscript, The Magnificent Dissections! by Greg Frederickson

I liked this dissection in particular since it looks like some kind of insect/creature when transitioning between the 2 shapes.

This model prints as a single piece without need for supports. It does take some gentle rocking of the hinges to break them loose initially. A small amount of cleanup around hinges may also be necessary.
