I recently had an email inquiry (and then a follow-up technique) from a reader of Sacred Geometry Design Sourcebook about how to replicate the “Flower of Life – with Second Harmonic overlay” illustration on page 87 using classic straightedge and compass techniques. Here is her illustration, with comments. The basic technique is to subdivide the underlying hexagonal/equilateral triangle grid by the number of the harmonic desired. Thanks to SEEW from Maryland for the contribution!
Recently, I had the pleasure of visiting the Zometool factory in Longmont, Colorado.
There, my favorite (hands down!) geometric toy, er, I mean modeling system, is manufactured. Paul and Carlos gave me a tour of the amazing technology where these wonderful plastic components are made by the gazillions. The secret of the hub, rumor has it, is the trained microscopic radiolaria that already understand the necessary geometry and amazingly eat away the parts of the hub that don’t look Zome-ish. You’re not buying that idea? Oh well… maybe there’s more to it than that… :-)
The primary purpose of the day’s festivities was to begin assembling circular ‘rosettes’ (note the white quasi-circular shapes with 6 yellow hubs in some of the photos) to be further assembled into a new art piece for the Denver Art Museum. (Stay tuned for updates on the blog page.) Here are a few photos from the fun, collaborative day with great music provided by Paul’s daughter Lizzy, and excellent Zometool assembling fuel provided by Carlos and others. I’m looking forward to seeing the finished project at the Denver Art Museum! :-)
Zometool, with the addition of green struts, can build many of the designs – both 2 and 3 dimensional – that appear in the pages of Sacred Geometry Design Sourcebook (SGDS) and other 2D and 3D models. Now, more than ever, this superlative modeling system (which is also the coolest toy in the geometric Universe, in my opinion) is a fabulous complement to Sacred Geometry Design Sourcebook.
The green struts allow for square root of 2 proportions relative to blue struts, which allow shapes like tetrahedra, octahedra, star tetrahedra, several more Archimedean Solids and MUCH more to be built. Amazing how adding another proportional system to the prior version seems to add many dimensions to the possibilities. (BTW, the feline model within the model is Cooper, our new kitten.)
Here are examples of some of Zometool models that appear in the pages of Sacred Geometry Design Sourcebook. I’ll be adding to these as I go on, so look for announcements in the monthly bulletin about updates to this page. This example, from page 236, shows the 2-D projection of icosahedral and dodecahedral cross-sections, and the underlying golden rectangle and golden-ratio-based geometric proportions.
Zometool Jewelry – featuring elegant chrome-plated Zome hubs – is now available! Nancy (our resident jeweler) says she can make these earrings with the bottom (Swarovski 6mm) crystal in a variety of colors in addition to the pink (rose) and jet black varieties shown here, including clear, aqua, blue, light blue, midnight blue, teal, green, purple, amethyst purple, and other colors and variations. Each earring features the unique Zometool hub (12 pentagonal holes, 20 triangular holes and 30 golden rectangle holes) with a metallic chrome finish. Chains and earring hooks will vary with styles.
This is just our first offering, so look forward to matching necklaces and other variations coming soon!
Note: These two pairs are now available. We’ll feature more items on GeometryCode.com and NancyBolton.com as they become available.
To buy a pair, specify the stock number, and send a money order or check to Intent Design Studio for $30 a pair plus $5 shipping to US addresses. Colorado residents, please add applicable sales tax.
Stock number CZ1: $30 + $5 shipping to US addresses
1 Pair Chrome-plated Zometool hubs, with Pink Swarovski 6mm crystals, silver hooks and silver chain
Stock number CZ2: $30 + $5 shipping to US addresses
1 Pair Chrome-plated Zometool hubs, with Jet Black Swarovski 6mm crystals, silver hooks and gun-metal plated chain
(The chrome ‘hub’ is about 5/8″ in diameter; the chain is 1″ long; the hook is 1/2″ long; the crystal is about 1/4″ long and the total length or ‘dangle’ of the earrings is about 2 3/8″.)
I recently started experimenting with Nanodots Magnetic Constructors (a 216 magnet set of remarkably strong (and fun!) little spherical (NdFeB) magnets. They are enjoyable to play with just from a tactile, sensory perspective, since they are like a set of high-tech micro-planets you can squeeze and morph in your hand like modeling clay … and the next moment, when you pull the amorphous mass apart, you get dynamic strings of metallic pearls that have amazing tenacity to maintain the connection to the whole. I’m just getting started in using Nanodots to explore my primary interest in geometric shapes.
Here are a few photos of Nanodots in 2D (flat shapes in a plane).
As you might imagine, if you make two shapes and put them close together on a flat surface, suddenly you find yourself with one shape! Symbolically, the magnetic principle abhors duality! :-) When you have smallish shapes in close proximity, but not so close that they join, you can rotate one and the neighboring shapes will rotate in tandem, almost like invisible gears; cool! :-)
I’ve made a few simple 3D geometries with Nanodots, but will need to spend more time and try a variety of polyhedra and other shapes. Interestingly, a few of the shapes (like the tetrahedron which moves immediately into a square and the octahedron which jumps into a more space-filling arrangement) are a bit tricky to hold (without some external constraint), since their geometries when made of magnetic spheres tend to fly apart and rearrange into more stable magnetic alliances. I think I see why the seasoned users make stable clusters and then make the larger shapes out of these smaller clusters.
Since their magnetic properties lend toward modeling with larger clusters that aren’t as influenced by smaller numbers of spheres, I’ll explore further with larger sets. Here are some excellent examples that others (mostly with larger sets than 216) have made.

There are LOTS of great examples (both videos and static images) of polyhedra and other geometric shapes that are superb uses of Nanodots here; enjoy!
