So, you're trying out the new Google Hangouts (which you can already enable in Gmail by the way) and you want something "cool" to show your friends... Google has you covered, as they didn't forget to include some curious hidden easter eggs in the new Hangouts.
For now, these only work on Google+ and the Hangouts Chrome Extension, which means we can't use them in the mobile version neither during video calls, but... do try them out. You just need to type:
- /ponies - a pony running across the chat
- /pitchforks - angry mob
- /ponystream - several ponies (but showing up only in your own window)
- /bikeshed - changes the background color for everyone
- /shydino - shows up a little shy dinossaur
- konami code (up, up, down, down, left, right, left, right, B, A, enter) - changes the local background (and if you have a chromebook pixel, it will also make the multicolored LED bar go into party mode for a while! ;)
