Not for people with neck problems

The arduino platform
has been the basis for a lot of bizarre gadgetry over the years, and
the audio ping pong project by Mike McCracken certainly stands up to
the best of them. The game is essentially the classic Pong with one
major difference—instead of using your hands and eyes, the game is
controlled with audio cues and head movements.

When the headphones are on, the player hears a sound (the ball) that
seems to be getting closer. In order to return "the ball" you tilt your
head to one side or the other depending on which side the movement is
heard. The challenge is to center the sound and return the volley. As
the contest progresses, the speed increases until you miss the ball or
you break your neck—whichever comes first. As you lie twitching on the
ground, a buzzer and a light from the machine will mock your defeat. To
discover just how stupid all of this makes you look, check out the
video below.
