Test folds: Square shifted twists

I’ve played a bit before with twists in non-round tubes and using them in models. These test folds are my first attempt to combine those with my diagonal shifts, giving two square tubes that are offset from each other. The offsets of the two square tubes are the same in both test models.

Square shifted twists 1 and 2

In both versions (as in my previous tests), the points on each face of the square tube all fall along a parabola. Because of the offset between the tubes, the vertex of the parabola is aligned with the focus of the twist (the point at which the paper converges).

Square shifted twist 1

In the first version, I tried a simpler version of the math that places the focus of the twist at the same height as the vertex of the higher parabolas. In this version, the shortest segments of the twist go through the focus essentially horizontally, giving some vertical separation between the two tubes.

In the second version, the focus is shifted down to eliminate that vertical gap, or at least greatly reduce it. This gives something that looks a lot more like the twists I used in my diagonal shift series.

New(ish) work: Curved-neck vase 3

This piece is a continuation of my series of curved-neck vases. The neck is a series of crimp bends to create the curve. This is from a couple years ago and spent most of a year at the Science Museum Oklahoma, but I didn’t get it posted then.

I like the look of these forms and how much more organic they are than many of my more purely geometric designs. Unfortunately, the series of crimp-folds along the neck is such a pain to fold that I’m not in a hurry to add any more to the series.

New work: Textural study vases 3 and 4

Continuing from my recent textural study vases, another pair of vases. The first has three inset bands tilted at different angles along different axes. As always, I painted the paper before folding it, so the locations of the bands had to be planned in advance.

The second is a larger deviation from the base vase shape, with several distinct steps between vertical columns.

Textural study vase 4

Here are the three painted vases in the series together, showing the common basic shape with differences in texture and pattern.

New work: Textural study vases 1 and 2

After a long absence, a few relatively simple vases exploring texture in folds and paint. I chose to use the same basic shape for these two vases so I could play with these effects.

Textural Study Vases 1 and 2

The first vase is folded from unpainted Elephant Hide paper. The neck has 15 pleats, which is just far enough from my normal 16 pleats to make the dimensions a bit annoying to work with. The 15 pleats allow me to make the base a regular pentagon, and the large unfolded panels curve enough to transition smoothly from 15 sides to five.

Textural Study Vase 1

The second vase is painted with a brushed texture similar to things I’ve used quite a few times before. Each of the 16 sides has a raised flange with several waves. The construction is very similar to a large vase I folded several years ago (see crease pattern), except for the added waves.

New work: Tilted horizontal shift vase

This vase is part of my series of geometrically distorted vases, incorporating a tilt of the main axis of the vase. This vase is similar to one of my recent models, and since that model I’ve figured out how to adapt the curved portions of the vase to keep the horizontal planes all closer to exactly horizontal. The shift in the middle uses the same pattern as my downhill diagonal shifts, with the angle chosen to match the tilt of the vase.

This model is the second in my series of curved-neck vases. These models use the same geometric crimp-bends that I’ve been using my geometrically distorted vases, but the series of bends creates the illusion of a curve. The series of bends is a lot of work to fold, but I like how this model has a different feel from the more strictly geometric pieces I’ve done for a long time.

New work: Tilted bent vase

This model builds on my recent offset bowl, where the model is based on a tilted cylinder. Here, I added curved folds and painted lines to the tilted cylinder, fitting it into my geometrically distorted vase series. The central bend is similar to my previous designs, and the top and bottom planes are also defined by sine waves to transition between the tilted cylinder and flat planes.

Interview in The Fold

I was recently interviewed by Ilan Garibi, and my interview was just published in The Fold:

Origami Designer’s Secrets: Rebecca Lynn Gieseking

Ilan has been writing this series for several years, and it’s an honor to be included alongside so many other great designers. Among other things, I talk about my design and folding process and my sources of inspiration, especially the interplay between art and science in my work. Also included is a crease pattern for my 2012 ornament:

New Work: Offset Bowl

Offset Bowl
Offset Bowl

Inspired by my diagonal shift pieces, this model is a test piece incorporating several diagonal planes. The base, central plane, and top edge are all defined by sine waves. Unlike my previous models, these sine waves create three planes parallel to the table but tilt the central axis of the bowl. This is fairly straightforward to do with all straight folds, and I’m exploring whether this concept can be used with curved folds in my more complex diagonal shift designs.

Crease pattern: Bend variation

Crease pattern: Bend variation
Crease pattern: Bend variation

I designed a variation to my crimp-bends last spring, and here is the crease pattern. The concept is similar, but instead of being based on two sine waves, this version is based on one sine wave and one straight horizontal line. In this variation, part of the flat plane joining the top and bottom tubes is exposed. So far I haven’t figured out a mathematically correct way to place the central line such that the joining plane folds flat, but it comes close enough to work in practice.
