a promising line of origami thought

from Origami Made Easy by Kunihiko Kasahara, Japan Productions, Tokyo/NY, 1973

"...So far, no book or other full treatment of abstract origami has appeared. But like other fields of endeavor, origami can certainly have main streams and branch currents, one of which can be abstract figures. As this field has yet to be explored, I present a few abstract origami here in the hope that they will inspire you to devote attention to what is likely to become a promising line of origami thought..." -Kunihiko Kasahara (Origami Ideas for Future Study)
