Models with Dubious Classification

This album gathers models whose classification (assignment of model type) is dubious, for example because it can be assigned to two types which are usually considered disjoint, because the traits used for classification are ambiguous, etc. Specific reasons are usually outlined in models’ descriptions.

Cookie Cutter - Christmas Tree

Cookie Cutter - Christmas Tree

This is an example of how the simple cookie-cutter design can be generalized by varying each side’s length and angles independently, and even applying curved...

Hemp Leaf (CFW 88)

Hemp Leaf (CFW 88)

Another simple modification of a hex twist by Shuzo Fujimoto. When used as a tessellation molecule, this design has later been rediscovered by multiple peopl...

Cookie Cutter

Cookie Cutter

This simple model looks like a cookie cutter, and if made with some stiff enough material (thick metal foil perhaps), could probably actually be used as one....

Well III

Well III

Third design in my Well series. The layout looks the same as Well I at first glance, but the central square is placed at a deeper level than all the rectangl...

Ampersand (CLU)

Ampersand (CLU)

In 2021, I went back to my Cross Lap Unit (CLU) from 2016 and folded this ampersand (&) character. The ampersand symbol, which is, strictly speaking, nei...

This snake is just a strip of paper that I cut off the side of an A4 sheet with a hex grid so that an integer even number of grid divisions was left on the r...

Well II

Well II

This is another approach to the subject I already presented in Well I, with the central square being larger and the arrangement of bricks around it having ax...

Tower of Babel (CBU)

Tower of Babel (CBU)

This is just a single long Conveyor Belt Unit (CBU) wound into a coil, but it looks like the Tower of Babel in Bruegel’s painting or the Guggenheim Museum.

Tie

Tie

I designed this origami tie in order to illustrate a point I’m going to make in a not yet published part of my series on origami classification. The point is...

Katniss (CFW 177)

Katniss (CFW 177)

This design by Shuzo Fujimoto represents a katniss flower (Japanese: おもだか, omodaka, also known as arrowhead in English). It falls somewhere halfway between a...

Well I

Well I

In this tessellation, rectangles are arranged in layers around a central square. I called it Well since it reminds me of a perspective view looking down a we...

Twisted Paper

Twisted Paper

This is a very simple design, not the kind of twists used in tessellations. Still, I think there is certain elegance to it. I find it hard to classify this m...

6<sub>2</sub> Knot (CBU)

62 Knot (CBU)

The 62 Knot is one of three prime knots with crossing number six. Though not as well known as the Trefoil Knot, it is also quite interesting. This origami ve...

Trefoil Knot (CBU)

Trefoil Knot (CBU)

In contrast to my earlier trefoil knot from CLU unit, which used a more elongated strip of paper and was shaped more like a clover, this trefoil knot is fold...

Möbius Strip V (CBU)

Möbius Strip V (CBU)

A Möbius strip consisting of a single Conveyor Belt Unit (CBU) twisted and locked with itself by both ends. This is the cleanest representation of a Möbius s...

Another attempt at folding the subject of Star of Bethlehem, this time using the Lucky Star molecule (invented independently with Fujimoto, Haligami and many...

Scroll of Time: 2017

Scroll of Time: 2017

I wanted to try something new this year, so I folded this model from thin parchment paper whereas most of the time I use much thicker papers. Modern parchmen...

Möbius Strip IV (CLU)

Möbius Strip IV (CLU)

The Möbius band (aka Möbius strip) is an interesting mathematical object, a single-sided surface. This origami version is folded using my Cross Lap Unit (CLU...

Heart (CLU)

Heart (CLU)

Origami heart made from a single Cross Lap Unit (CLU), using a similar technique as my Ichthys. Metallic paper with acrylic paint.

Ichthys

Ichthys

Easter is coming so with fluffy bunnies and cute chickens aplenty, it’s good to also add this fish to the pack.

Single-Module Modular Heart

Single-Module Modular Heart

This heart is made from a single module which is a modification of 90-degree unit (independently discovered by me and others), so it’s like a modular design ...
