Accused of being fake, witchcraft and simply impossible..
This kinetic sculpture is inspired by the unlimited freedom of 3d printing,
it wobbles and turns with a slight movement of the hand.
Now give it a good spin or puff of air and it erupts in erratic and wild behavior.

This is the 5cm / 2" version, see the Gyro the Forms section for other shapes and sizes.
Corner stand available separately, or get the complete set below!

NEW!
Now also available as a pendant/keyfob!
In both Extra small and Small

Instructions
It is composed of four concentric cubes, each one spinning around a different axis.
The model needs some minor assembly:
Each inner cube has two knobs which need to be placed into the corresponding clamps in the parent cube. It's easiest to start with the inner most and continue outward.
And then... spin it away !

Notes
Do not be alarmed if your cube will not run smoothly at first!
Because of minor variations as a result of the printing process,
some need to wear in a little but will loosen up very quickly.
In the example video I am blowing on it to make it move, it's that smooth.

Be a little careful with (the assembly of) the Alumide version as this material is slightly less flexible/robust than the Strong & Flexible materials.

A default set consists of an Alumide Gyro the Cube and a White stand, you can change the materials in your cart later. +

A replica of Cobb's totem from the film "Inception". As a below review has noted, and from my own version, the top works very well, and spins upwards of 90 seconds before toppling. You just might be in a dream.

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 .

Over The Top is a world-record 17x17x17 Rubik's Cube. It makes quite pretty patterns. It can take many, many hours to solve. The puzzle was first presented live to the world at  at the New York Puzzle Party Symposium, Saturday Feb. 12th. The YouTube video was be published after that event, and the record was accepted by Guinness World Records.

Dodecahedral sibling of Gyro the Cube.
Same principle, more faces, more rings and more fun ;-)
Made of five nested dodecahedra, each one is limited to rotate about it's own axis.

This is the 6.5cm / 2.5" version, see the Gyro the Forms
Experimental corner stand available here

Instructions
For tighter clearances it is printed with the hinges out of place. So this model needs a little manual assembly. Each element has two "knobs" which need to be "clicked" into the corresponding "clamps" in the parent element.
It's easiest to start with the inner one and then continue outwards.
And then... rotate away !

As seen on blog.objet.com, this is the updated model of the one shown in video. Now you can open the doors! This is the mid size model -- 2cm long. NO ASSEMBLY REQUIRED!

Own the Tesla Valve, as per the original design of Nikola Tesla, patented in 1920. See the video below to observe the valvular conduit in action.

Nikola Tesla invented this valvular conduit as a valve for his engines. Materials at the time were pretty bad, and valves were unreliable. Tesla figured that by removing any moving parts from a valving mechanism, he could create a simpler and more robust valve. The hook regions in the Tesla Valve reroute the fluid back in on itself creating a bit of resistance. All the hooks added together do a good job of arresting the fluid, especially when the gas or liquid is pulsed through the valvular conduit.

When you hold the valve in your hands after opening your shapeways package you are possessed of a strange kinship with the historical figure of Nikola Tesla. Pressing your lips to the valve, and blowing through it, you see that it actually works. In the resistive direction your breath is nullified to a mere whisper by the Tesla Valve. And in the non-resistive direction, air flows through unimpeded. It is startling the effect, and to think something so interesting as this valvular conduit was made so long ago.

I made this valve to commemorate Tesla's birthday on the 10th of July, 1856. Owning this valve is a way of recognizing a forgotten genius of unparralled creativity.

A detailed full color model of each of the planets, gas giants, and major moons of the Solar system, to (logrithmic) scale.
This set includes the 20 largest objects in the solar system (bar the sun).
All surfaces are reproduced from NASA imaging.

For size reference, Jupiter is 25mm (1 inch) diameter, and Earth is 12.76mm (1/2 inch) diameter.
(A photograph of some of the planet models can be seen on th page for this subset of planets. Photos of this full set coming soon.)
This set is designed for use in orrery or other models of the solar system, and so to best present all planets while preserving scale, the scale has been compressed - a logrithmic scale instead of a linear scale. This means that if the model of a moon of Jupiter is larger than the model of Mercury but smaller than Mars, then you know that the real moon really is larger than Mercury and smaller than Mars, But the size diference is compressed - Jupiter, which is really more than ten times Earth's diameter, becomes only twice Earth's diameter, etc. This logrithmic scale allows all planets to be clearly visible together, while at the same time still indicating their sizes relative to each other.

The set contains all planets, a dwarf planet, and eleven moons:
[In order of appearance in the photo above, right to left]
Mercury
Venus
Earth
 - Moon / Luna
Mars
Jupiter
 - Ganymede
 - Callisto*
 - Io
 - Europa (attempt no landing there)
Saturn
 - rings of Saturn
 - Titan
 - Rhea*
 - Iapetus*
 - Dione*
Neptune
 - Tritan**
Uranus
 - Titania*
Pluto**

All objects have a 1.6mm (1/16th inch) hole at the south pole, for a brass axle (or a toothpick).

What color is a planet - is it color of its surface materials, or the colour of its atmosphere from space, or the color of the surface being colored by the atmosphere filtering light from the sun? The appearance in this set attempts to be that of the surface with moderate atmospheric influence, (with the gas giants depicted as the atmosphere and surface being the same thing). For example, this means that Venus depicts the features of its surface, but they are tinted somewhat by its atmosphere. Similarly, Earth and Titan show ground features, but some areas are tinted and obscured by atmosphere.

In areas where the model surface is more detailed than the most detailed NASA photography (such as Pluto), the overall surface appearance conforms to what is known, but finer textural details are speculative. (Or, if there is an atmosphere, it is shown as particularly thick and opaque over the unmapped area.)

*Due to hard limitations of the Shapeways production, these minor moons are sharing the same surface map. They were chosen because they have a similar surface, and/or their surface is largely unknown.
**For the same reason, Pluto and Triton, which have a similar icy surface and not much photographic detail known, also share their surface map.
(The alternative was to not include those moons)

Big Boulder is a blatant case of twisty puzzle extremism. 1 core, 60 centers, 140 corners and a whopping 150 edges. That is a lot of pieces. And to make it more complex, this puzzle jumbles too, which means that some moves may be blocked by other pieces. This puzzle is based on the geometry of a Pentagonal hexecontahedron. You may want to look that up on Wikipedia. The object of the puzzle is to scramble it and then solve it to a state where each color only touches itself or black.

A 3D rolling ball maze with a bone-like matrix in a clear cube| pirate pocket puzzle |Reach the treasure to solve the maze

A pirate chest recently washed ashore containing a never-before-seen hand carved puzzle. The carvings on the chest indicate that the puzzle is a 3D maze map through the caves on Dragon Fang’s island where the vast treasure from the pirate ship Black Lion is hidden. You open the chest only to find that the main body of the maze looks eaten away to the “Bare Bones.” Luckily, there is a clear case in the chest as well, and a small brightly colored ball that will help guide you. The ball fits into the maze at the round mouth of the cave maze in the corner of the cube. The maze then slides into the clear case; it is a perfect fit. You shove the sturdy case with its precious map into your pocket. The question is, can you solve the mystery of this maze and find the treasure? The carvings on the chest show that your goal is shown as another round ring with the remains of an “X” along its border.

To get there, roll the ball along the bones of the maze to try to reach the treasure. Your ball can travel up, down, fore and aft, port (left) and starboard (right) to travel through the maze. The clear walls allow you to easily see exactly where you are in the maze, and which directions can be tried next, but getting there is harder than it looks. Argggh, there have been plenty of “Bones” cleverly placed along the tunnels to trip up any unwary pirates and keep them from reaching the treasure. These can lead you astray or plunge you into a deep pit.

The “X Marks the Spot” where your treasure is found. If you reach the treasure you are not done yet matey! You have to return safely back to the mouth of the cave. Be wary though, there are new perils on the way back, and many pirates have never found their way back out. The true brave of heart can enter again to see if they can find the treasure again, this time, faster!

Good Luck Maties!

This model is a two pack of the Bare Bones mazes, each with it's own maze ball. The 3D maze fits snuggly inside the 2 inch by 2 inch by 2 inch clear plastic cube. The clear cube also serves as a display quality case for this clever pirate work of art. This clear plastic display cube is sold separately, and is available for around $3. Use the link below to purchase it with free shipping. Note that this plastic cube display case is part of this rolling ball 3d maze puzzle and is required for the proper working of the maze. For this two pack of mazes you will need to order two cases.

Medium Size BCW Maze Puzzle Display Case for Bare Bones 

Display Case for Bare Bones for UK Customers

Start by setting one of the “U” shaped halves of the clear case on a table with the sides of the “U” facing up. Before putting the “Bare Bones” maze in the case, orient it so the circular mouth of the cave (the one in the corner) is on the bottom. Place the ball on the bottom of the “U” of the case, such that when you next slide “Bare Bones” down into the case half, the circular mouth of the maze goes over the ball. Next carefully slide the top half of the case on. The photos and video above illustrate how this is done. You are now ready to start solving this maze puzzle.

Many a pirate has been lost in the cave, but have no fear - you can slide open the two halves of the case and the ball can easily be shaken out to start solving the maze game over again.

You can easily color the ball to make it show up even better in the maze. A quick and simple method is to use highlighter markers, or Sharpie colored markers. Enamel spray paint for plastic models also works very well. Spray paint was used to color the ball in the photos.

The clear case is very sturdy, so you can carry this maze puzzle around in your pocket or your bag. When not being played, this unique new type of maze can be displayed as a fascinating work of art. Set it on your desk or shelf, everyone will be curious to know what it is and want to give it a try.

This new maze design uses thicker rods for the maze. They are also rounded off so the maze structure looks like a skeletal matrix of linked up bones.
