Welcome to my Snapology Origami page.  Just a place to share the products of my obsession.  The projects within are based upon the folding and joining strips of paper.  I originally started by learning from the works of Heinz Strobl.  Since then I've pushed myself and started to design my own creations.  Hope you enjoy. ​

Off-Topic Again

I've been meaning to tackle a few new Snapology ideas, but I keep getting derailed with my laser cutter.  I really like how this project turned out.  I laser cut some wood and some acrylic mirrors.  On the outside, a dodecahedron made of a beautiful curly maple.  On the inside, a kaleidoscope of "stars".

Finding Time

Ugh.  It's amazing how hard it is to find the time to update a website.  I've been busy with my latest obsession, laser cutting on my Glowforge.  It's amazing all the things you can do.  The only downside is my garage smelling like a fireplace.

Anyways, I've added pictures of my latest work, a "cube".  The quotes are because I'm pretty sure the model is not a geometrically accurate cube.  In this case I'm taking advantage of the flexibility of the cardstock to achieve the design.  I also posted pictures of a piece based on the principles of dual solids.  You can see more in the Polyhedra section.

I've also added an OTHER section to the site that will be for things I'd like to share, but aren't snapology related.  I've been doing a lot of work with my laser cutter.  The first is my model that shows the relation between an icosahedron and the Golden Rectangle.  I've had a fascination with both polyhedra and the Golden Ratio.  It wasn't until recently that I read an article showing the relation between the two.  Mind blown!  

Also, not math-related, but still a fun project, a mahjongg set made of walnut and curly maple.

Paper Engineering and Sag

4/10/2018

For those of you taking on snapology origami as a hobby, I thought you might be interested in one of the issues I've had with bigger projects.  It's something that doesn't crop up until your work sits around for awhile, which is sag.  It's amazing to see how the quality of paper can make a difference when it comes to larger projects, especially over time.  You start to see how the choice in cardstock can make a big difference. 

As an example, I have two of my Klein bottle pieces shown below.  In my prototype (red) I was trying to keep the weight down since the structure was fairly tall, so I used a thinner, lighter cardstock.  The other one (dark blue/silver) I used a much thicker, heavier cardstock.  Initially both Klein bottles came out okay, but over time the prototype has started to sag.  Between the thinner cardstock and, I'm guessing moisture absorption, the prototype didn't hold up well over time.

The moral of the story?  If it's a choice between lighter weight vs. stiffness, go with thicker, stiffer paper for large projects.  Either that or have a collection of saggy, listless models.

The cylindrical base began to collapse in on itself at the bottom. (above)

The "tube" at the top of the prototype began to lean to the side. (left)

The other model (below) has held up much better despite the heavier cardstock.

Snapology Origami Kits

Recently I did a sit down session with a few colleagues on how to do snapology origami.  During the session they mentioned that a cool idea would be for me to make kits.  Well, here's the results!

Each kit has the necessary pieces for a particular project, all of them pre-cut and pre-folded.  They come in a laser cut box which doubles as a stand for when the project is finished.  On the back of the box is a website that has the step-by-step assembly videos.

I'm really excited about these kits.  They've been fun to make and I'm very happy with how they've come out.  So far I've made two kits, one based upon an icosahedron (see right) and another based upon a truncated icosahedron (soccer ball design).   We'll see where this idea goes.  Hopefully there will be more to come.  Keep posted!

A Whole New Perspective

What happens when you have a friend who loves Snapology AND has a 360 camera?  Absolute coolness!  My friend and owner of Geometiles, Yana Mohanty, took a picture of a modified version of my dodecahedral 11-holed torus using her 360 degree camera.  The end result is to the right.  I soooo want a 360 camera now!

KUSI Good Morning San Diego

Wow!  I got to make an appearance on KUSI's Good Morning San Diego.  They heard about my winning art entry at the 2017 Bridges Art Exhibition and had me come in for a short interview with Jason Austell.  It was a fun experience!  Great people at KUSI.  In fact, my cameraperson was a Marshall Middle School alum, the school I teach at.  Talk about a small world. The only downside was that by the end of the interview Jason accidentally called me Richard, not David.  My friends are going to be calling me Richard for at least a month.

Here's the interview.

2018 Bridges Art Exhibition

I belong to a group called the Math Teachers' Circle in San Diego.  They had seen my Snapology Origami work before and encouraged me to enter into the 2018 Bridges Art Exhibition since it was in San Diego this year.  Lo and behold, of my two submissions they accepted one of them, my dodecahedral 11-holed torus.  You can see both of the pieces in more detail here.  A much bigger surprise was that it won in the category of Best Textile, Sculpture, or Other Medium!

A big shout-out to the San Diego Math Teachers' Circle, in particular, David Patrick from The Art of Problem Solving and Yana Mohanty from Geometiles, for encouraging me to enter my piece.

    I'm a middle school math teacher.  I also consider myself a Maker.  I love anything that involves designing, building, and creating.  My current obsessions are using my Glowforge laser cutter and, of course, Snapology Origami.
