Demi Dubbel, created between 1995 and 1997 was a visual moo in which children collaborated both on- and offline.. This was before alfa worlds and second life.
The idea was to trigger the imagination of children. Inspired by Bruno Bertelheim the idea was not to give literal possibilities for identification. So we sketched evironments and provided the children with tools, but the character was only in the story in the text. Demi Dubbel was not depicted. Every chld imagined her differently, like charcaters in books.
Children collaborated in groups of 5 childen in front of one screen. This was because we did not have more computers. The good side effect was, that locally discussion were vibrant. Children were reading to each other what happened and discussed what to do next.
