San Diego and Kupka

I just got back from a visit to San Diego. 

I must recommend the wonders of Balboa Park. 

Inspiration station.

One highlight there is the San Diego Museum of Art. 

My favorite painting there?  Oddly enough it was not a landscape, but Blue Space by Kupka.

Of course to see a painting like this in person tops this internet found image. 

But I can still ask the question...

what is this painting about? 

It reminds me of ice, a flower or something of this world... and yet it is not.
