Whomever came up with this is a genius. I'm calling it this year's Wayne's World scene.
The new $1000 iPhone X comes with a feature called Animoji that takes advantage of the phone's TrueDepth camera. It analyzes your facial expressions and mirrors those expressions in a dozen different Animoji in the Messages app. You can then create your own Animoji and share it with anyone using an iOS device, Mac, or smartphone.
But if you have hours to kill, you can take the Animoji one step further and start a group Karaoke with your iPhone X holding friends. In this case, have them sing Bohemian Rhapsody.
