'Artifact' in the sense that it's an artificial structure that couldn't 
occur naturally. In general I wouldn't describe molecules as artifacts. 
I guess buckyballs and buckytubes count as both as they do occur in 
nature, albeit rarely. And I wouldn't class a single crystal as a 
'molecule' either. :P

I guess it is a bit of a grey area.

Publicity; like a nanoscale ad poster... I guess it makes people aware 
of it. They'll be bringing out a low carbon-emission version next just 
to get the climate change crusaders off their backs.
