Project Seed

OK, a game called "Block the Block, "where you walk down the street and there is a camera attached to your back. The camera recognizes if there is a body behind you and your screen gives you an indication of if you need to walk to the left or to the right in order to try and prevent them from passing you. The goal is to try and get a stranger to walk behind you and not pass you. If they see that you are doing it on purpose, you lose. If they pass you, you lose? Lose points? IDK, but that's the general game mechanic.
