An #origami #airplane collected by Nguyễn Hùng Cường. He believes it is #Vietnamese and was created during the 1955–75 war.

Dave Mitchell sees a similarity with the #traditional @origami Flounder https://www.origamiheaven.com/historyoftheflounder.htm

Every few years I have a go at wet-folding #origami. This is Sleeping #Fox by Nguyen Tu Tuan, wet-folded by me.

Tu Tuan says that every time he makes it, it's different: this is common with shaping wet-folded @origami.

Made a OR logic gate in #origami.

Pseudo-@origami cranes in Hanoi, Vietnam.
Look closer and the “#origami” #cranes appear to be made of two plastic pieces slotted together.

A real treat: On Sunday I was one of the lucky ones to attend a zoom workshop where Beth Johnson taught the Baby Grand Piano by Patricia Crawford. This is the result of a fast paced hour of folding, without additional refinement. A fun fold and a great model from the early seventies!

Me he reencontrado con este autorretrato que me hice hace ya ¡cinco años! y sigue siendo de mis dibujos favoritos.

Las cosas han cambiado mucho en cinco años, tengo más canas y menos tiempo, pero me gusta esta versión de mí mismo.

The Collapse of the Cylindrical Wedge

#origami @origami

That is, a section of a cylinder where the planes intersecting are not parallel. The eye of the vortex appears to be one of the foci of the ellipse. Round objects added to stop the eye from normalizing the shape, as it *will* do, no matter how many times I've told it not to.
