What is "art" to you?

I asked this question to a few people today after seeing Mr. Alan Cooper's brief thoughts on art's role in design, or the lack thereof. The answers I received aligned with his definition of art being personal expression. 

But what of art's relation to design? Is there a place for art in terms of software, web, or end-to-end experience design or, as Mr. Cooper states, does this idea essentially differ and distract from the true needs of design work?
