This is a LaunchBar action that implements the same underlying data as my python class and web app.
Put the .lbaction bundle in ~/Library/Application Support/LaunchBar/Actions/ and it should work!
Live Feedback can be enabled via the LB Actions Editor, but if you enable it, the submenu for emoji variants (i.e. different skin tones and genders) won't work. (the > will show but the right arrow won't work). I have disabled Live Feedback as the default.
