Fun ziz-zag modular origami unit
The PHiZZ module is probably the easiest modular origami unit to fold, and it is also very versatile. PHiZZ stands for pentagon-hexagon zig-zag unit, because you can make a shape made of pentagons and hexagons.
The shape below is make of 12 pentagons. 
From the excellent origametry.net, we learn how to fold the PHiZZ unit.
To put the units together, follow this:
It is nice to build shapes out of 3 colors, which means that we can construct a Hamiltonian path through the shape, which is a path that visits each vertex exactly once. See the “football” below (12 pentagons, each surrounded by 5 hexagons). If you choose one color to ignore, you can think of the hamiltonian path as the one that is made of the other two colors.
