Along with his colleague Keiko Nakazawa, Chatani developed Origamic Architecture, a variation of kirigami (itself a variation of origami where cuts were allowed), where you only needed an X-acto knife and a ruler to create complex 3-dimensional structures out of a single sheet of paper.

Origamic Architecture sculptures range from (the relatively simple) geometric patterns to famous buildings’ facades. It’s like 3-D pop-up greeting cards, but much, much more complex. While looking at the examples below, keep this in mind: everything’s done with the simple cuts of the knife.
