I tried start a discussion on Engestrom in the General Forum.
To make the subject my own I drew up the activity system on MDF then laid out some chess pieces. Ideally I would do this outside, on a beach perhaps, with people and objects.
This is how I'd develop a concept board in three dimensions, with real instruments.
I've done this with a Youth Theatre before developing a script for a video, the entire process enabling me to get my head around the subject so that any audience who then view the product of my work get it too. (hopefully).
This is web 1.0 thinking, telling. Web 2.0 should engage your audience earlier in the creative process, so that it is a collaborative, shared, and these days a fluid, even an open outcome.
