The book “The Analysis of Performance Art. A Guide to its Theory and Practice” by Anthony Howell puts forward a method of teaching performance art as a discipline distinct from dance, drama, painting or sculpture. There are exercises in the book which are different ways of mixing the three primaries of action; stillness, repetition and inconsistency.
I did not do an exercise this day, but link to an exercise I did in 2009 when I was supposed to stand still for an hour in a shopping mall, but was thrown out before an hour had passed. http://exercise-of-freedom.blogspot.no/2009/02/stand-still-for-one-hour-in-lively.html
