'Tweet Me 4 Moji' is a Twitter bot with a far more benevolent and silly purpose than many other bots on the social media site. Rather than acting as an aggregation machine, auto-retweeter, or fake follower, Tweet Me 4 Moji will provide users with emoji-covered images of themselves and their friends -- or anything else that they submit.
The bot uses a facial recognition algorithm to scan images and find the faces in them. It will then cover all the faces within the image with emojis. More than just covering every face with the same smiley, though, Tweet Me 4 Moji can assess the facial expressions worn within the pictures. It will then cover the faces with the emoji that it believes most closely resembles that emotion.
