Rewind Twitter and replay it in real time
Ever watched a recorded TV programme and wished you could see what the reaction was on Twitter? Now you can!
It's a mobile web app that lets you rewind your Twitter timeline and see tweets from the past unfold in real time
So you can jump back to the time a TV recording had actually been on, and then watch what people were saying in sync with the programme.
You can do the same thing with certain hashtags (there's a list anyone can use or users of the paid-for service can choose their own hashtag to capture - whether it's a TV programme, news event or conference).
Anyway, if you go to www.tweetrewinder.com, you can watch a video that explains how it works and sign up for the beta version (which works best on a mobile phone right now). But here are some screenshots. (You can follow Tweet Rewinder on Twitter, too).
