For my groups artists collaborate project we have taken the idea of creating a written/illustrated story. The way we plan on going about this is starting with a candidate, asking them to write a line or two, then draw what happens in their written part of the story; then hand the sketchbook to the next person asking them to do the same, each person adding their own touch to the story. Page by page, line by line, drawing by drawing, eventually a story will be pieced together and hung up/strung together in comic book panel form.
