I noted Hockney among those I counted. I can add Chris Billington, David Rolt, Joanna Carrington. All modern, British, artists who make spectacular work. But, see, they make art. A room-full of blue crystals has about as much to do with art as a pile of rotting sack-cloth and dung. Just because you claim it as art in poncy words does not make it so.
In, it should be noted again, my opinion.

I will also say that, at least the blue room is cool-looking. It isn't art, but it is cool. Dung and sack-cloth is just revolting.
