The list is = number of facebook users + ~10 normal emoticons(
No, not kidding, you can take any user's profile picture and turn it into an emoticon. Take anyone's profile find his profile ID and post it to chat like
[[PROFILE_ID]], and his/her profile image will turn into an emoticon. E.g. -
Try it. :)
Update: Finding the user ID is a bit tricky.
For the users who didn't setup a username, their profile page looks like this -
https://www.facebook.com/profile.php?id=100002872529, and you know that's the user ID.
For those who have setup an user ID - go to their profile page, view the source of that page with your browser(For chrome, you press Ctrl + U), search for this exact text -
profile_owner and you'll see something like
"profile_owner":"100002872529". There you have the ID.
This is the fastest way for me, if anyone has even faster way, please post. :P
