This is a bit on the funky side:
The emoticons were generated on the Windows 8 client machine's built-in Messenger.
The green faces on the right showed up in the Messenger thread on a Windows 7 Enterprise that hosts the working desktop (just-in-case system). All Messenger, Twitter, E-mail, and other essential services are running side-by-side at this point.
Looks like the age-old emoticon in Windows Messenger is getting a face lift! :)
