I mostly build reactive environments, which could be called robots or simply machines.
The machines are constructed the way that the observer automatically becomes a participant simply by her or his presence.
Therefore any person in a certain range does not have a choice for or against interaction.
The machine senses you with or without your will and reacts according to your actions.
The emotions of being in the presence of a self controlled but still artificial something is my most important topic of research.
I never know how the behavior of my machines will be like before and during I build them.
The programming of my machines is never finished and does change depending on the observed behavior of the visitors during exhibitions.
