Info and purchasing: http://shpws.me/D6g
I designed this pendant, I call it Twin Rail Mobius - with balls!
To buy the pendant, please visit http://www.shapeways.com/model/162900/ you will also need to obtain some (upto 31) 6mm (1/4" works too) balls
Its a kind of kinetic math art double möbius (mobius or moebius depending how you spell it) band or strip like structure with rails forming a continuous double loop ring track for ball bearings to travel around. I bought some 6mm chrome steel ball bearings and retro-fitted them. Chrome steel balls can be 'blued' by heating with a gas torch, see http://www.youtube.com/watch?v=OwlMhOmg91A
As a piece of jewellery, this pendant is quite large (46mm max diameter) and is more suitable for a man.
Rapid Prototyping also makes use of 3D printing, but I prefer to create decorative and unusual objects. One of the benefits of 3D printing is that an item such as a mobius strip can be made without complicated tooling or destroying the master when a mould is made as the process is additive and the object is built up layer by layer. The item is literally grown from nothing!
Some have asked if this is my own invention - yes it is.
Others have asked if this is an illusion - no, it is not.
And thank you to Assimilate71 for the comment "Escher is impressed. Nice design" :)
