I am interested in a political art, that is to say an art of ambiguity, contradiction, uncompleted gestures and uncertain ending - an art (and a politics) in which optimism is kept in check, and nihilism at bay.

The drawings don't start with 'a beautiful mark'. It has to be a mark of something out there in the world. It doesn't have to be an accurate drawing, but it has to stand for an observation, not something that is abstract, like an emotion.

It’s always been in between the things I thought I was doing that the real work has happened.

My grandfather was a member of Parliament for 40 years. Obviously we're talking here South Africa, a whites only parliament. I grew up in a family that was very involved with the legal battles against apartheid—the great treason trials in the 1950s and early '60s, and later with the legal resources center that my mother founded. My father was involved with a number of very prominent cases that had political aspects to them, whether it was the inquest into the Sharpeville Massacre, the death of Steve Biko, or one of the trials of Nelson Mandela.

I'm interested in machines that make you aware of the process of seeing and aware of what you do when you construct the world by looking. This is interesting in itself, but more as a broad-based metaphor for how we understand the world.

The absurd, with its rupture of rationality-of conventional ways of seeing the world-is in fact an accurate and a productive way of understanding the world.
