One of the most important elements of Caio-ness I wanted to keep was that left to right reading, where one form draws you... this movement in what is otherwise a fairly still art, that sense of pulling the eye. It involves a sense of time. To me that's esoteric and magical and playful, and if a painting doesn't have that, to me it's just canvas and paint. If it does have that, then it rises above its materials.

I was never exposed to art school. I grew up in an artist's studio. I was exposed a lot of studio time between of my father and a great painter I studied with in Barcelona. That was my art school, as Europe was.

If you come every day or every month to my studio, you won't see that much change, but if you come once a year, you'll see big new categories opened up.

Most people draw from the mind, not the eye. They draw the idea of a table or a face, not what's in front of them. We don't actually see the line of the jaw as a line and we don't see an eye as a perfectly outlined almond shape.

My forms are not abstractions of things in the real world. They're also not symbols. I would say that my job is to invent these forms and to put them together in a way that keeps your interest, to give the forms a quirky identity so you can engage with them, so you realize there's an inner intelligence or logic. If you stop asking what they mean, or what they remind you of, and just look at them for 29 seconds, you find that they want to explain themselves and show you how much every tiniest detail is related to the whole.

I underwent a whole process of slowly letting go of idiosyncrasies and habits and embellishments and everything extraneous to the essentials that I'm unwilling to let go of. I never dreamed that I would be making black-and-white paintings with so little embellishment. But it's been liberating in many ways to let go of that and yet see what I did want to retain.

Painting is something that requires a lot of time - it's not just one good idea out of art school.
