A flexagon is a folded paper structure that flexes and unfolds to reveal many different faces.

Flexagons are usually divided into two groups:

• two-dimensional or flat flexagons that flex to reveal multiple faces, and
• three-dimensional or rotating rings of tetrahedra or polyhedra that rotate through their centers, sometimes called flexahedrons.

The fun part of flexagons is discovering the hidden faces and learning to operate them smoothly and with confidence. Like all book structures, flexagons can be used to strong or weak effect. A flexagon is the book equivalent of the dissolve shot in movies. They are powerful at showing how one image melds into another.

In "Four Seasons" the same tree trunk undergoes seasonal changes.

In "Album" I go from a baby, to a young boy, Vietnam soldier, clown, and finally, a happy partner in a gay union.
