5OSME: 5th international conference on origami in science, mathematics and education


I thought some on this blog may be interested in learning about the 5th international conference on origami in science, mathematics and education.

Please also see:

If there is sufficient interest among those who register for the conference, I may arrange for a small group of 20 people to visit Singapore schools the week of 19-23 July 2010.

5OSME (5th international conference on origami in science, mathematics and education) is scheduled for 13-17 July 2010 at the Singapore Management University in the heart of Singapore. English is the major language in Singapore, so there should be no difficulties in communicating with the locals.

Since Southeast Asia is a fair distance to travel for those of us in the northern hemisphere, we are extending 5OSME to include not only a research conference, but a folding conference and a merlion design challenge.

Separate messages have been posted about these events, but this message will include information for all three components:

See the following links for the program for 4OSME:


Origami enthusiasts/folders/creators from around the world are hereby
cordially invited to submit diagrams of their models for publication in
a diagram book in conjunction with the 5OSME convention.

Contributors whose models are selected for publication will receive a free
copy of the convention book. In caseS where the diagrammer and
creator are different persons, both will be acknowledged in the book,
but only the one who submitted the model for publication will receive a free
copy. If the contributor is unable to attend the convention, the book
will be sent to him/her via regular mail.

Due to copyright issues, only models that have not been published
elsewhere will be considered.

Please include your name and email address (for quick communication).
Contributors will be notified via email whether their models have been
chosen for publication. The organising committee will make the selection
based on the level of difficulty, the limitation on the total number of
pages in the book, quality of the drawings and subject matter.

Please submit your diagrams to

Deadline for submission: 31 December, 2009

Content of submission:
Title of the model (required)
Name of the creator (required)
Name of the diagrammer (if different from creator)
Country of origin (required)
A complete step-by-step guide of how to fold the model (required)
A black and white photo of the completed model (optional, .jpg, .gif,
.tiff format)
A crease pattern (optional)
A short introduction of the model, creator, inspiration, paper
recommendation, acknowledgment etc. (optional)

English is recommended, but we accept explanatory text accompanying the
diagrams written in other languages as long as the diagrams are clearly

Subject matter:
Any subject matter: living organisms, inanimate objects, modular, etc.

Preferred file format:
Pdf, MSWord (.doc), Inkscape (.svg). We apologise that we are only able
to accept electronic submission. If the diagrams are hand-drawn, please
submit a scanned copy with a minimum resolution of 600 dpi.

Page size:
A4, with 1 in. (25.4 mm) margin on 4 sides.

Model difficulty:
Any level. The organising committee will test fold all the models. If we
are unable to reproduce the creator's result, it may affect the model's
acceptance for publication.

Standard origami notation. Please refer to for guidelines.

Copyright policy:
The creator retains the right to the model as well as the diagrams, which
will not be published elsewhere without prior consent of the creator.
However, by submitting the model to the convention book, the creator
gives permission to anyone to freely fold and duplicate the model for
non-commercial use. Please refer to the website for
a detailed copyright policy.

Any queries related to the diagram submission can be directed to


You are invited to participate in an Oriami Design Challenge.
The theme is the Merlion, and the challenge is open to everyone.
Participation is free and there will be no restrictions on the number of
models you may submit.

The Merlion, originally designed as an emblem of the Singapore Tourism
Board, is an imaginary creature with the head of a lion and the body of a
fish. The lion head represents Singapore's original name "Singapura" or Lion
City in Sanskrit. The fish body comes from Singapore's ancient name of
Temasek meaning "sea town" in Javanese.

The Merlion at Merlion Park is one of the few Merlion sculptures seen around
Singapore. Pictures of this Merlion are uploaded at:

A page for photos of the models and their CPs will be created soon on the
5OSME website. Once your model is ready, please take photos of it from
different perspectives and send them to Merlion Challenge at: Include your name, and country (city) of residence in your
email. Please also provide some information about your model, e.g.
paper used, techniques applied and size.

This is a design challenge and there are no prizes. The winners will be
decided by voting based on the picture submitted and uploaded on the
website. Voting is open to everyone, and further information on voting will
be put up on the website.

The pictures submitted will only be used for the purpose of the Challenge.
Any requests for commercial use will be referred to the model creator.

Deadline for submission of pictures from participants is 13 June 2010.

Thank you. We look forward to receiving your submissions.

Best regards,

The 5OSME Organizing Committee

Is origami limited to construction from one sheet of paper? Are card models considered to be something else? I've been inolved with developable and expandable curved surfaces for many years, but nobody makes any links to origami. Do you consider Gehry's Bilbao Guggenheim museum origami?

Hi Patsy!

Re < Is origami limited to construction from one sheet of paper?

No, there is modular origami made from several to many sheets of paper, which then are combined to make a model.

Re < I've been inolved with developable and expandable curved surfaces for many years, but nobody makes any links to origami.

Do you have photos I can see of what you have developed?

Re < Are card models considered to be something else?

I'm not sure what you mean by card models, but in fact, I am working on a potential cross school building project as part of 5OSME, using business cards. in a later message I will post some links to projects spearheaded by Jeannine Moseley, who built Menger's sponge and a business card model of Union Station in Worcester, MA.

Please see for papers presented at 4OSME.

More later.

Google "card models" and you will bring up a world of people who make complex scale models out of card stock (stiff paper). This technique goes back hundreds of years.

What I'm talking about are shapes shown in the following paper from 4OSME.

"Building Free-Form Structures From Sheet Material"

I write CAD software that can be used (one part of which) to create curved surfaces which are unwrapped into flat patterns that can be CNC cut out. Most of these are large scale structures that include framing. The frames are cut out and the unwrapped plates are marked with the locations for the frames. Everything is CNC cut out of aluminum, steel, or plywood.

If a surface has double curvature, you can subdivide the surface until you able to flatten it without too much stretch for the material. All curved surfaces can be made from flat material if you subdivide the surface enough or if the material can be stretched. (A little stretch goes a long way.) Some people build curved structures out of plywood and they call this "tortured" plywood construction. The big question is how much stretch is allowed before the shape becomes unbuildable or the material fails.

I have some pictures, but I can't insert them here. One is a sculpture that was designed and built in Alaska - Anchorage, I think, but I can't find a picture of it online.

Another interesting project I worked on was a half-dome in a cathedral that needed to be painted. Instead of painting the dome, the artist created a small picture that was transformed to the shape of the dome. The dome wasn't perfect, so exact measurements had to taken. I had to recreate the almost dome shape on the computer, divide it into 15 degree wedge sections and unwrap it flat. The digitized picture was mapped to those pieces and plotted (using pigment-based inks) on artist canvas. (Giclee printing). These pieces were then glued to the dome. The big unknown was whether the mapping of the 2D artist picture to the 3D dome model or the unwrapping of the doubly-curved wedge shapes would cause enough distortion to be visible.

This is the finished dome.

Constructing 3D shapes from 2D patterns covers many different fields. Unfortunately, too many people are rediscovering the wheel.
