3.4.6.4 Tessellation, done with an interesting methodology

This tessellation is quite fascinating, for several reasons, which I hope I can elucidate here.

First, here’s the underlying tessellation- a 3.4.6.4 semiregular tessellation. (Image used from Totally Tessellated, which is a site well worth visiting if you like tessellations.)

Normally (for me, anyhow) folding a 3.4.6.4 tessellation requires using quite a bit of paper to flesh out all the pleats, intersections, and other parts; so necessarily, one must use a piece of precreased paper with quite a few division in it to really do the pattern justice.

The real beauty of the way this design has been folded lies in the use of elements on both sides of the paper; so the pleats coming away from the open-backed offset hexagonal twists on the back turn into the pleats leading into the triangular twists on the front, with a minimum of wasted space.

Joel Cooper uses this technique very often, in his “flagstone” style tessellation patterns. While this design does not pack the twisted polygons as close together as Joel prefers, it still uses the same types of concepts- putting the twist elements on both sides of the paper, and using the interconnecting pleats as a sort of “middle layer” to do more work with less paper waste. This is a somewhat difficult concept to execute in paper form, at times, so I am very pleased to see more people picking up on the idea and running with it like this.

I’m also quite enamored with this pattern because of the use of spacing. It’s not a big secret that I’m particularly fond of open patterns that let a lot of light through them- it’s not just because I’m lazy and like to avoid close, dense packing of patterns (although that’s quite true!) but I really enjoy a good balance between light and dark, shadows and brightness. By using these multiple layers (or at least conceptually, multiple layers) the pattern has a much richer depth to share with us when it is backlit. Besides the 3.4.6.4 tiling, the twists, and the overall circular feel to it, we also get wonderful bowtie patterns linking all the sections together, as well as quite a few different areas of paper thickness- which, especially if folded from a light paper like white unryu, would really make a striking difference in shading.

This is a great design, and I’m really rather smitten with it! Good work!
I highly encourage you to check out additional work by Miguel, on Flickr or on his wonderful blog, Doblando Papeles.

Some really nice work recently from Jorge Lucero, of Brasilia, Brazil. Jorge was one of the exhibitors at the Tessellation exposition there last month, and his work was huge- and very impressive!

Since then he’s made some new work, including this multi-hydrangea tessellation. Very good stuff, and very precise- it was a joy to look at his folding there, as it’s absolutely accurate. (Although that is perhaps what one would expect from a mathematician…)

Thanks for sharing this, Jorge!

Oschene’s 10 Pointed Twist Star

Philip Chapman-Bell (aka Oschene on Flickr) has been doing a lot of fascinating exploration of twists lately, including some spectacular 16 sided chrysanthemum shapes and this particularly delicious 10 pointed twist star.

True to form, after sorting all this information out he went further and published a full sequenced crease pattern (SCP) for this design, and released it under the CC License. I am a big fan of his SCP work- it’s clear to see and understand, and is a lot more thorough than a basic CP while being easier to create than a full diagram set. And I have to give him a big hand for releasing his work under a CC license so others can freely use, share, remix, and reuse his designs. Thanks for sharing this with us, Philip!

Here’s some more of his stellar work:

I just uploaded a new PDF of instructions for folding a Double Pleat Hexagon tessellation; you can download it here.

It is released under the CC Non-Commercial Attribution license, which means you can do anything you want with it, other than sell it for $$$, or go around saying it’s your own. (which hopefully you’d be nice enough to not do anyway!)

Let me know what you think. Thanks!

Lightbox Testing: Joel Cooper, RAW vs. JPG

Hey there- I’m doing some testing with a lightbox setup, and I could use some feedback. I’ve got a few photos in my photostream- more to come tomorrow- and I would like to know how they look at full resolution to you. good? bad? fuzzy? clear? I’m leaning towards shooting RAW files and doing a lot of post-processing, but it’s a lot of work to do. Maybe I’ll need to switch to film or actually go out on a limb and find someone with a 12+ Mpixel digital camera to do this thing right.

Anyway, take a look- http://www.flickr.com/photos/origomi or look on my Photos Page and click on “Recent Photos” to see them.

Thanks for your feedback.
