For Shapeways' #3DSiri design competition. Perhaps this is what Siri looks like... my interpretation in the form of a tag style silver pendant. Also available in a selection of plastics.
A different design is also available on Shapeways.
The above images are rendered computer images. I believe that the design will look even better in Shapeways silver. I expect that the recessed areas won't be highly polished and the upper areas will be - giving more texture to the design and highlighting the details attractively.
Images of the design can also be viewed on unellenu's website
