Adventure Draw
Published in 2012, Adventure Draw is a collaborative story and drawing book where children (and adults) complete partially finished stories by directing the narrative and completing the illustrations. I have participated in numerous public events and led school presentations where groups of 10 to 100 children and adults participate in over-sized recreations of the book to collectively create their own story.
It's tons of fun. Check it out: http://adventuredraw.com/

I've created a limited line of children's furniture and interactive game wall art. Pictures speak better than words: http://elastichorizon.com/
