I have attended to the string puppet workshop oriented by Stephen Mottram and Marcelo Lafontana at ESMAE Porto in April 2012.
A 10 days workshop divided into building methods and the art of manipulation.
The first part we had to build a marionette based on a kit developed by Marcelo Lafontana and the second part of the workshop we had the opportunity to learn and apply the manipulation methods of a marionette. Stephen Mottram shared some of the most important principles of the marionette biomechanics.
