I love playing table tennis, but my backhand topspin is average at best. I'll play for an hour and grow tired of chasing wayward balls, knowing that I'll never have a smash quite like Peco from Ping Pong. Never mind -- now I can cut loose with a game of "Ping Pong FM" instead. The modified bats, which have contact microphones inside, log when you've hit the ball and remix music accordingly. Exchange slices too slowly and the song will drop to a lower tempo; likewise, driving the ball with some vicious top spin will cause it to speed up. You can try to match the beat or purposefully remix the music in weird and wonderful ways -- it's entirely up to you.
