The core Motion Sonic Project is a wristband that you strap on like a watch. The prototype I saw wasn't terribly refined, but it's early days still, so I won't judge it for its bulky appearance. Once you put the device on, it hooks up to a tablet and speakers and starts producing sound in sync with your movements. Sony had five different demos, one of which had me punching the air as loud, booming noises came out of the speaker in sync with my flailing arm. Another had me tapping my body to produce xylophone-esque sounds. And, of course, I did the robot.

The demo was frivolous and fun, but the idea of moving your body to manipulate audio isn't a new one. Any improved tech to make that more precise and engaging is worth keeping an eye on: A new way to manipulate music you're playing by moving parts of your body could lead to some weird but cool new sounds.
