Star with Spirals, designed by Meenakshi Mukerji

Meenakshi Mukerji featured some of my origami on her guest gallery page, including this model.  Then I realized I hadn’t posted this one on my blog yet, so here it is.

Regular readers have probably noticed that I feature an awful lot of models designed by Meenakshi Mukerji.  That’s because I have four of her books!  The Star with Spirals is featured on the cover of Origami Inspirations, which I would say is the best of the four.  Although, if you’re reluctant to commit, you might consider one of the Exquisite Origami books, which are cheaper because they’re in grayscale.

Three-Form, a model designed by me.  Some of the component cubes are taken directly from Meenakshi Mukerji.

I was looking through my photos, and I realized that there are several large models that I never got around to sharing.  This is one of them.  The Three-Form consists of 24 little cubes, assembled into a larger mathematical design.

This one is inspired by General Relativity, Einstein’s theory of gravity.  At the time I was reading Sean Carroll’s textbook on the subject, and I was lamenting how difficult it was to visualize the mathematical concepts therein.

Announcement: I now have a flickr account for my origami photos!  Now the images are bigger, and you can find them all in one place.  There are also lots of photos that I haven’t (yet) posted on my blogs.

Arrow Illusion, version 2. An original design.  My hand is in the photo to show that this is a real mirror.

Over a year ago, I designed an origami arrow that points in the opposite direction when looked at in a mirror.  I wanted to revisit the design, and make it easier to fold, because this is basically the most popular origami thing I have ever done.  Below, I show detailed diagrams, and a sneak peek behind the curtain.

Toroidal Cube, a design by me

In case it’s not clear what’s going on in the photo, the model is in the shape of a cube, and we are looking at it directly onto one of the vertices.  However, the vertex has been cut out, and there is a triangular hole in its place.  There is also a triangular hole on the opposite end, so that you can see directly through the cube.  The triangles aren’t really triangles, but they look triangular from just the right perspective.

Today’s model was inspired by the regular toroid.  You may have heard of a torus, which is the shape of a donut, or a mug.  A toroidal polyhedron (aka a toroid) is a polyhedron which is also a torus.  A regular toroid is a toroidal polyhedron where each face has the same number of sides, and each vertex connects the same number of edges.

Tomoko Fuse’s Simple Sonobe 12-unit Assembly Plus Alpha, from Unit Origami: Multidimensional Transformations

Fuse has a series of models that consist of basic polyhedra, with extra pieces of paper attached as embellishments.  This model is a cube (made of 12 pieces of paper) with a pyramid added to each face, and 3 spikes to each vertex.  All in all, that’s 42 pieces of paper.  This is a pretty neat idea.  Since it is made of three distinct types of units, it defies the usual convention of making modular origami from many identical units.

This one’s a fairly old model, apparently made in 2013.  I gave it away as a gift so I don’t know if it’s still living, or deceased.

Lilia, by Ekaterina Lukasheva. I’m not sure I got the name right, but I’m absolutely sure about the author.

In the past year I’ve been dabbling a lot into other kinds of origami, such as traditional origami, tessellations, and minimalist designs.  But still, it’s good to make some modular origami models.  This is a kusudama model of very standard design.  30 units, 5 colors arranged symmetrically.  Although, I actually made 2 of the 5 colors identical, which is a cheeky way of making it slightly asymmetrical.  This was made as a gift for a relative.
