All you have to do is send an image of your face to Tweet Me 4 Moji and the bot will take care of the rest.
Once you’ve send a picture, the quirky invention will cover your face with a corresponding emoji and tweet you back with the new image.
@MattNavarra Here's your 'moji, Matt Navarra ⭐️??

What makes Tweet Me 4 Moji particularly amusing is that it will put emoji on all faces it can recognize in an image, including those of your friends.
