I would really love that we all start using some open chat standard (Like XMPP) so WhatsApp, Telegram, etc. could talk to each other.
Or something like email, you could have [email protected] or [email protected] and that would be your 'chat address' and all clients could talk to each other
You could use Font Awesome with bootstrap, it includes classes for some neat icons and also classes to make them spin; http://fontawesome.io/examples/ see "Animated Icons"
Implementing that .btn-spin yourself wouldn't be too hard either, couple lines of CSS...
