'Simultaneousness' is a technique. Simultaneous contrast is the most up-to-date honey of this technique in this field. Simultaneous contrast is visible depth – Reality, Form, construction, representation. Depth is the new inspiration. We live in depth, we travel in depth. I'm in it. The senses are in it. And the mind is too.
