Animojis, Apple's custom, animated emojis only possible with the iPhone X and its TrueDepth camera, are either the cutest, or most disturbing, thing to come out of Cupertino in years.

When Apple introduced Animojis with the iPhone X in September, they were an instant hit. We couldn't wait to turn our 10 second audio iMessages into chattering monkeys, snorting pigs, and freaked out aliens. There are 12 Animoji options in all (with more sure to come), and each one can match your facial expressions and head turns in startling detail. Which, naturally, makes them a perfect fit for another obsession: karaoke.

First tested by Fast Company'sHarry McCracken in this tour-de-force clip below, Animoji Karaoke marries your favorite tunes with Animoji animations.

Creating them, though, is not that simple. The only way Apple's iPhone X Animoji's can track your face is through the iPhone X's TrueDepth camera, which uses depth information from your face to keep the animation in sync with your mouth, eyes, and all the rest of your facial muscles (it can track blinks, winks, grimaces, frowns and wide-eyed looks).

To create Animoji Karaoke, you must play the music loud enough for it to be picked up by the iPhone X's microphone and then, yes, you have to lip sync for the TrueDepth camera to create the Karaoke effect.

iMessage Animojis are limited to 10-second clips, but iOS 11's screen recording feature will let you scoot right around that limitation. If you don't plan on posting these on YouTube, you can record whole songs. Otherwise, don't try publishing full-length Animojis of Selena Gomez' It Ain't Meand posting them on YouTube. It is fun, though, to share 10 second karaoke animations with friends on iMessage and social media.

To create our Hit Song Animoji Supercut, we recorded the audio and Animoji lip sync simultaneously and combined them in Apple's iMovie video-editing app.

It's not perfect, but you get the idea.

This Animoji fun doesn't stop with music. You can record some of your favorite movie lines or speeches, as long and you speak (mouth the words) and emote in front of the TrueDepth Camera. It won't be long before someone is taking President Trump's classic lines and applying them to one or more Animoj characters, which include a fox, a robot, a monkey, an alien, a pig, a dog, a unicorn, a panda, a chicken, and a poop emoji.
