Previously I’d spotted a little fox waving flags popping up on my hangouts chat window on my android when I received an excited message but had been unable to work out what caused it.
Today it happened on my desktop hangouts and we did a little experimentation and found that the string “Yay!!” (case insensitive but two exclamation marks required) was the trigger. We also found that the celebratory flag fox only seems to appear the first time the string happens in a chat. After that you get cheering yellow man in various different forms:
This just leaves me to wonder what other little context-specific easter eggs are hidden away in hangouts.
