A few years ago some of my coworkers used a Raspberry Pi to instrument our work foosball table. They had badge readers so all the players could badge in, and IR sensors for autoscoring. They found some open-source foosball leaderboard software that they ran on the Raspberry Pi as well, so we had an auto-scoring, auto-ranking foosball table. Best Raspberry Pi project I've ever seen :)
