posed as a media-related one – here chemical, there electronic – is what you shift to the visual object. Do these media-related, radical changes nevertheless play a role in your thinking?

Heimerdinger: I can’t say much in response to that. There is a vast repertoire of media and possibilities within these media. And I always have my idea first; after that I reach for the technical possibilities, or medium, needed to realize that idea.
