In 2005 she was part of the group of larpwrights creating the collective Evolution Events. The intent was to make larps that were different by Dutch standards, like ruleless larps and one-shots, both of which were rare in the Netherlands when starting out.
She is primarily interested in character design and the way individual character narratives shape the overall story, and in the motivations for (and effects of) player choices on how the larp plays out.
