I've always been fascinated by haiku, and the launch of Drunken Haiku by a good friend gave me a brain wave. There's a massive number of updates on Twitter, some of them must be unintentional haiku!
A couple of hours later, Accidental Haiku was born. It sits on Twitter looking for messages with the right syllable patterns. It's not always perfect at counting the sounds, and being Twitter there's lots of fluff, but if you watch it update I guarantee some gems.
