Everyone loves Karaoke! With Karaoke VR you can sing along with your friends in a virtual world. Choose any karaoke song that is available on Youtube. The spectator mode allows friends to sing along too while you perform in a variety of custom made environments.
I use a spectator camera to allow audience participation while the person in VR is immersed in a virtual stage with a video panel they can read the lyrics from. The videos are pulled from youtube giving a wide selection of songs to choose from.
