In connection to his artistic work, Mischa Leinkauf faced quite often unrealistic project tasks. On the one hand in terms of legal barriers, while trespassing to find the right location for shootings, for instance, and on the other hand in terms of his own physical possibilities. How to perform a handstand on the top of a church, reenacting a stunt from 1921? How to appropriate a highly secured architectural system like the subway system of Berlin in order to work there for weeks? Mischa Leinkauf’s lecture gives an insight into the development of his projects and his strategies for overcoming boundaries in order to realize artistic works.
