As unearthed from the iOS 11 GM build that unexpectedly (or perhaps intentionally) leaked out last night, iPhone 8 will make it easy to customize all-new animated 3D emoji based off your own facial expressions picked up by the phone’s depth sensor and the front-facing camera.

According to 9to5Mac, Apple is calling these Animoji, describing them as bespoke “animated messages that use your voice and reflect your facial expressions.”

To customize how they animate, you’ll make facial expressions into the depth-sensing camera. “Users create them from within the Messages app on iPhone 8,” writes the blog.
