There are lots of games or humour memes on twitter, my current favourite is “Historical Tweets“, and the above is one of my favourites of the favourites.
The basic premise is to encapsulate a historic moment in twitter’s 140 character limit, most, like this one, use the contrast of the historic moment and the modern technology to raise a laugh.
You can follow them on twitter, and you can submit your own attempt at a historical tweet.
Oh and there’s a book coming – but not until April 2010.
