During a press conference at their new San Francisco HQ, Twitter has unveiled a brand new design for Twitter.com (and also the iPhone and Android apps) – Lauren has already covered this in detail here. It’s a HUGE update, at least aesthetically, but also has some new features which are worth checking out.

Twitter has put together this video showing how the new design will look and work – which is great if you don’t yet have access to the Twitter.com revamp.

The video, titled Twitter: Yours To Discover, shows off the user interface switch, which is basically a complete reboot.
