Hi Colin, you have some wonderful futuristic ideas for illuminating the watch dial, I do hope you manage to develop these. Regarding Perl, it is not something a that I have heard of, but having looked it up on the net, I am well impressed. It is way above my understanding when it comes to computer programming, but you have obviously done a wonderful job. I think you, svorkoetter and DJW should get together, you would make a great design team!
