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!

It's all pulled together from open source components and you can download the modified phirehose code here. Now if I could just learn to write good haiku myself…
