On Day 3 of 5-in-5, C. Anderson Miller and I decided to collaborate on a board game. We ended up with a game we call Subwoofer Tactics. It’s a turn-based game in which players compete to knock their opponent’s pieces off the game board by vibrating the board with a subwoofer. Read more about the game here (including the official rules for tournament play). Watch the video below to see the game in action.
