A new app called Dance*Cam has been released to promote the sequel to the immensely popular Kinect game, Dance Central 2. The app lets you select a song (previews of dance tracks like Far East Movement’s Like a G6 and Sean Kingston’s Fire Burning are available) then record someone dancing. Then, the app works its magic, processing your uploaded video in about a minute and “dancifying” it, reversing moves, repeating certain steps, adding in some cool custom animation and so on, all in sync with the music. Upload the video to Facebook and challenge a friend to a battle, which joins two videos into one so other friends can vote on who can break it down the best.
