Tsuru Rose, or Rose Crane, by Satoshi Kamiya

Instructions for this model are freely available online, for instance see this video.

This is a neat model that combines ideas from traditional origami, and origami tessellations.  (I last talked about tessellations here.)  You start out by folding a “rose” right in the center of the paper.  The rose isn’t a tessellation, but I believe that in principle it could be turned into one if you repeated the rose infinitely.  But here we just have one rose.  Then we fold the rest of the crane around it.

By the way, there’s a trick to making those wings curve so smoothly.  I press the wing against a toothpick (the side, not the point).  Then I slide the toothpick along the wing several times until it curls.
