Well its time to confess. The Riverwash 1k invitro will be my last 1k. I've been doing 1ks for over 2 years now and its time to move on. Thanks to everyone who voted for it and thanks to Riverwash organisers for asking me. Although I said I wouldn't publish code anymore, I can't think of a better way to bow out of 1k coding than to publish the last one so you can download the code here.
I hope in the last 2 years, my efforts at 1k and my publishing code have encouraged and enabled a few people to get going with 1ks.
