65mm hole to put your hand through, very light, entirely hollow! Many eyes!

Now available in a few different flavours, including in a split cuff form: http://www.shapeways.com/model/113902/polyoptic_bracelet_split.html

 This is a pair of sprockets for making a polargraph drawing machine.  These are gears designed to drive 12mm pitch beaded cord - like from a roller blind. Have a look at www.polargraph.co.uk for more information.

4.2 cubic centimeters of glorious hollow stainless steel, shot through with a beautiful radiating pattern of holes (the "eyes").

Great in gold plated, but also big and funky enough to make a statement in the bright summer colours!

Simple and handsome squared ring. This model is 3.5mm wide and the inside face has rounded edges, but is mostly flat, so fits more closely to the finger.

Crenalated ring with text (optionally) imprinted onto the faces of the fins. 5mm thick. This is a beefier version of the my Sun Sprocket Light ring.

Voluminous ring for making a statement. A wide band for comfort and stability. Totally smooth edges, cavernous interior.

Round banded design
