Road of Knives is a "battle blog" wherein Shawn Cheng, Matt Wiegle, and other artists take turns drawing monsters fighting each other.
So this is how it works: Shawn draws something. Matt draws something that will fight it. Shawn draws his thing fighting back. Matt draws his thing fighting back and maybe tripping over a statue. Then maybe Shawn's thing kills Matt's with the statue's head. Then Matt draws a new thing. Shawn's surviving thing attacks it. And so on.
Though not exactly an exquisite corpse, it is exquisite, and there are many corpses.
