"Elegance?" 

"Pardon me, Your Honor, the concept is not easy
to explain--there is an ineffable quality to
some technology, described by its creators as
a concinnitous, or technically sweet, or a nice
hack--signs that it was made with great care by one
who was not merely motivated but inspired.  It is
the difference between an engineer and a hacker."
