In Living 3D

Now this is cute:

A new scanning technique allows expectant mothers to hold a life-size model of their unborn, developing child.
Data from ultrasound, CT and MRI scans are converted into 3D models, which can then be 'printed' as a plastic representation of the developing baby.

(From New Scientist.)

Although it could be taken too far: imagine growing up with representations of your foetal self in jars lovingly preserved amongst family photos. Wonder if it could be scaled up to model organs too? A 3D model of your brain would make a great desk ornament. Or why not model your heart, for the ultimate Valentine Day's gift?
