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.

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

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 .

The iShark is an iPhone 'gramophone.' It magnifies the tiny speaker on your iphone when you pop it in the slot in the iShark's back (and also making your iPhone a dorsal fin). The sound emerges from the iShark's mouth. The blue color image is a suggested paint scheme, but you can paint it to match your favorite species. It has been modeled hollow to save cost to you.

Easy opening of ketchup packets, salad dressing packets, etc.
Simply slide a standard x-acto blade into the slot and clip a thin keyring through the hole.
Slide the corner of the packet through the slot and there you have it!

Gear Shift is based on an idea by Bram Cohen. This puzzle has eight gears around a cube. All gears can turn together. But it is also possible to pull the gears apart in two sets of four. Each set of four can be turned individually. And there are three ways to split the gears. The object of this puzzle is similar to Rubik's Cube: scramble it and then try to solve it.
