3D Printing
I am not sure how I missed the slow migration of 3D printing into the consumer world. I read a WSJ article on the topic today (WSJ link, might need a subscription).

Found a good NYT article on the topic.

Here is someone who sells art objects printed (I am not sure that is the right term) on 3D printers: Bathsheba Sculpture.

Very Cool!
