Ahhh the good old heptagon, much maligned-good design. Phillip Chapman Bell posted two crease patterns recently one a septagon crease pattern for a poof and the other a circle with an inscribed heptagon pattern for a container. The poof one I havn’t done, but his circle container inspires love of directional crease patterns. The finished container is strong and aesthetically pleasing. I’ve been playing way to much today with these tricky sevens. So if you have the chance go visit
and attempt his marvelous designs.
Seven Pointed Star Bowl
The heptagon poof
Minor varient. I just inverted and rotated the tips.
I’ve been back to making boxes lately; I just havn’t posted many of them. This container starts from a square. The sides are columnlike and the box fairly sturdy. I recommend 8″ paper that is stronger than cami, a square from a brown paper bag would do nicely. Link to diagrams is here http://flickr.com/photos/christine42/1236250648/
It took awhile, but here they are. This is a selection of photos from the exhibit “it’s all in the fold” coordinated by Bill Drendel. My pieces are in the second row. The third row starts with models folded by Ty Perez and then has Chris Palmer’s work. The fourth row is Bradford Smith, Lang, and LaFosse. The menger sponge was folded by Joshua Koppel and the tessellations on the wall are done by a Mrs. Hanson whose husband was also in the exhibit.
Although there was a lot of fascinating and beautiful artwork my favorite pieces were…
They are Nishimura circles, a collection of simple, but elegant architectural folds from Peter Seller?, and a silk tessellation from Palmer.
The rest of the photos will be posted to flickr within a few weeks.
I’ve been revisting an old design to use as a framwork to modify. When I am finished this piece might be technically called a corrugation. If I pulled on either edge it would pull apart. In other words there are no twists or locking mechanisms. This creates an interesting framework, but also means that humidity wreaks havoc on the design. The next one I do will be constrained on the outer edges, reinspired by Ben Parker, to better hold in the 3d design. This is not a poof, but a recollapsed model.
… some time later…
After seeing young Ben’s work I couldn’t remember why I didn’t keep with spread squashing (I never squashed successively like he did). I used a single spread squash when I folded the tree of life
As I work on the new piece the answer comes. It is not a clean squash. My symmetry is slightly askew and each successive squash gets worse. I may try with a paper other than elephant’s hide. I will post the current design when finished.
I’ve been asked how I do my tessellations. To address this I’ll explain two approaches and include a picture of a tessellation that utilizes the approach.
1. One way is to deform paper as I am making pleats/folds or after I have created a flat pattern I push the paper in so it is 3 dimensional.
2. Another approach is to create patterns and then treat them as a flat sheet of paper and overlay another treatment. I didn’t start designing these tessellations this way, but discovered it along the way and now use it almost exclusively. To hold the tessellations as I work I clamp them.
Eric Gjerde, the talented tesselator and blogger, has entered the ranks of the published. Now mere mortals cannot buy the book just yet, but with bated breath we wait. I realize the vast majority of you reading this blog know who Eric is, but if you don’t here is his blog
Reserve ahead, because, to my knowledge he is the first American too create a book on tessellation basics, and his book is going to be sweet. http://www.amazon.com/gp/product/images/1579909795/ref=dp_image_0/002-2187515-5652026?ie=UTF8&n=283155&s=books
You can get it for less than $13 dollars on Amazon, less than a few specialty coffee drinks and a scone. Teachers this would be a great resource to have in the classroom and a must for anyone who is an origami officianado.
At times with tessellations over the last year I have felt like I am hitting a brick wall. While I really like this design it feels redundant.
Folding, for me, has been about a process of discovery, but it also pushes my natural impatience with myself.
The back is almost identical to another tess I did recently called “Count?” What I do enjoy within the constraints of the template is that some very minor pushes entirely changes the one sides hexagonal faces.
