Defining creativity

At a recent innovation conference, I ran across an interesting definition of creativity:

Creativity = constructively deviant behavior

Here are some dictionary definition, none of which get to the heart of the matter nearly as well:

"Using imagination rather than imitating something else. Generation of ideas, images and/or solutions."

"The process of developing new, uncommon, or unique ideas."

"The production of previously non-existent information."

"The ability to produce something new, to generate unique approaches and solutions to issues or problems or opportunities."

The winner in useless defitions goes to "The ability to create."

Can you do better than "Creativity = constructively deviant behavior"?
