The best triply periodic minimal surface ever!

I put a bigger one here.

The filigree design over the skull symbolizes ever growing renewal over the ghost of the past. This is the original design as featured on Kickstarter. It became their #1 most funded sculpture project of all time. Small is pictured sitting in the hand. See pic of all 3 sizes together for comparison.

The nocturnal (or nocturlabe) is a very old instrument for telling time at night by measuring the stars. While concept is ancient, this design is all original. It is fully functional (all dials move properly) and meant to be worn as a pendant. This is now available for sale, as it has been tested and works nicely.

How to Use the Nocturnal:

The top of the nocturnal is where you see a bit of a ring around a spike. This ring can be strung with a chain and makes it possible to wear the nocturnal as a pendant. When reading the nocturnal, this end of the piece should always be up.

Your first step is to set the outermost dial on the date. The months are shown as letters, with January and December at the top, and the progression of the months running *counterclockwise*. Note that the exact position of the letter actually marks the middle of that month. Look closer at the piece and you will see the line that separates the months between the letters.

Now, hold your nocturnal up to the starry night sky, making sure that the date is still properly set. Locate the North Star centred in the hole in the middle of the Nocturnal. Then use the central dial (the one that looks like a pointer) to point to the two stars at the end of the bowl of the *big* dipper.

Once you have this all set. Look closer at the pointer and you will see that within the pointer is an eliptical ring and within this is a smaller pointer. This smaller pointer points to a roman numeral, which shows you the time.

Note again, that the roman numeral is centred on the middle of the hour. So, if the little pointer points in the centre of the numeral, it is in fact half past.

So now you can tell time at night without a powered time piece. This is great for night owls, vampires, and those who appreciate a gothic or steampunk look.

If M.C. Escher had owned fidget toys, he would have worn "One ring to rule the ball" as a pendant. A single, continuous line contains a small ball that makes orbit after mesmerizing orbit but cannot escape, always held down in four directions. Available in solid, durable stainless steel with optional antique bronze and gold plated finishes to fit any context, "One ring to rule the ball" now also includes a free rubber necklace so that you can confuse your mind any time the fancy strikes you! One customer echoes many others in saying, "I couldn't put it down. This thing is just too fun!"

Purchases by those gracious customers have now paid for the design time on this piece so it is available on a pay-what-you-want basis. Ordering from this page contributes 5$ towards continuing work such as the new, even more impossible "One ring to pwn the ball" (just released October 18th!) which can be found at http://www.shapeways.com/model/145172/one_ring_to_pwn_the_ball.html and the open-source "Ultimate Desk Toy" at http://www.shapeways.com/model/109166/ultimate_desk_toy.html .

A theorem walks into a bar...
The Klein Bottle is a mathematical joke: a surface with only one side. This one feels just right in your hand and opens bottles with ease and style. Built to last in steel, it's the perfect touch for any math fan's kitchen.

Yes, it really works!

Klein not-a-bottle-opener is here.

The design is based on the classic Celtic-style knot symbol for the World Tree from Norse mythology, Yggdrasil.

Inside the leaves you can see a small sphere of blue. If you look reaaally carefully, you could notice that the continents in the blue ball are in the shape of Pangea and not our current distribution.

Interlocking gears in a steampunk theme. These standard sized gear dice will keep your game turning (figuratively speaking, they do not actually turn...)

With percentile die.

This pendant features a mobius style spiral that can enclose a 6mm ball which jingles and jangles when worn.

If you'd prefer a right hand spiral, please see; http://www.shapeways.com/model/169011

NOTE:
Shapeways have decided that this model is unprintable with the ball enclosed.
This model will take a 6mm steel ball which can be fitted by gently forcing open the spiral... see video.
A 5mm ball is available here; http://www.shapeways.com/model/172759 or simply use a suitable (4.5mm-6mm) ball bearing.

The tale of the sneak eating it's own tail, where did it end?

Diy Base for all your character fan arts, or original character art. Paint this figure to your every needs.

This is a three-dimensional Union Jack.

After some light sanding the parts will fit together very snugly, without any need for glue.

I've colored this one with Sharpie brand permanent marker, which appears to work well and not transfer to the white parts of the model too much.
