Pajarita Tessellation (zoom in)
The Pajarita is a classical origami model which seems to be especially beloved in the Spanish-speaking parts of the world. In this tessellation, I places little Pajaritas all over the plane.
The molecule uses a 6×6 grid and is derived from my Propellers Tessellation. Note that the molecules are not placed one directly above the other, but each row introduces a shift of one grid unit to the side. This is necessary in order for the pleats going up from the molecule to connect with the pleats going down from the next. Connecting these pleats also makes the use of a rather interesting kind of sink necessary. In order to collapse this molecule easier, large grid spacing and thin paper are recommended. In this particular rendition, I used Kraft paper.
