The definition improves if you add "and is created for that purpose", though maybe still not without holes. As an example of your kids' mess, check out Tracey Emin's 'My Bed' [1], it's basically just a mess, but by deciding it is art and exhibiting it for that purpose it becomes art. But when it was in her house in the exact same state.. not art, as it wasn't intended to be. [1] http://en.wikipedia.org/wiki/My_Bed http://en.wikipedia.org/wiki/My_Bed
