An exquisite corpse is a collaborative drawing, where one person starts a drawing and then folds over the paper so only a small, unrecognizable portion of the drawing can be seen, then another person continues the drawing from that portion, folds over the paper and passes it on to another person, and so on and so on, until there isn’t any paper left to be drawn on. The paper is then unfolded to reveal a freaky, mutant drawing that is a combination of everyone’s styles.
Epic Exquisite Corpse is a huge version of this. It’s already huge with over 73,000 sections already drawn, but that’s out of a total of a million possible sections, so it’s going to be insane when it’s finished.
