I think I’m greedy, but I’m not greedy for money – I think that can be a burden – I’m greedy for an exciting life. I want it to be exciting all the time, and I get it, actually. On the other hand, I can find excitement, I admit, in raindrops falling on a puddle and a lot of people wouldn’t. I intend to have it exciting until the day I fall over.

In fact, most artists want to make things a bit more difficult for themselves as they go along, to challenge themselves.

If you are not playful you are not alive.

I think we seem to remember things in still pictures. I never gave up on painting. When they said painting was dead, I just thought, Well, that's all about photography, and photography's not that interesting, and it's changing anyway.

What the art historians had forgotten is that in Chinese, Japanese, Persian, and Indian art, they never painted shadows. Why did they paint shadows in European art? Shadows are because of optics. Optics need shadows and strong light. Strong light makes the deepest shadows. It took me a few years to realize fully that the art historians didn't grasp that. There are a lot of interesting new things, ideas, pictures.

Water in swimming pools changes its look more than in any other form its colour can be man-made and its dancing rhythms reflect not only the sky but, because of its transparency, the depth of the water as well. If the water surface is almost still and there is a strong sun, then dancing lines with the colours of the spectrum appear everywhere.
