I think art as defined by beauty is in the eye of the beholder, art as defined by monetary value is in what people with money to spend are willing to pay for it - and art is actually all about creativity and the way it can provoke thought in it's audience.

I struggle with the 'invisible nothing', but remember one of my grandparents favourite saying here (regarding fools and their money, lol) - and I'll admit that Tracey Emin has challenged me, until I began to look at it as representations of emotional states as much as anything else.

Interesting. I always enjoy your art pieces, thanks.
