Kinect Fun Labs: Musical Feet

Co-developed with Microsoft, Musical Feet is a Kinect Fun Labs title featuring an augmented reality experience that creates a piano on the floor of your living room. Play tunes alone or in groups and share your compositions online. Players can now step their way through their favorite songs.

"Make music with your feet! Select a sound (musical instrument, animal, or even your own voice) and dance across a giant virtual keyboard! Ham it up to become a Music Feet maestro, and share recordings with friends and family!"
