Recently I had the chance to test a RSS reader software with an interesting feature that seemed very interesting to me: the "autoplay" feature, this means that the application by itself goes from news to news.
I thought that it was very interesting idea for offices, public places, etc. so I thought that a web version could be very usefull, without having to setup the software. etc so this weekend I played a little with javascript and php and here you have the result

Right now it is just a working prototype but the idea is that every user could set up his RSS of choice, look, etc. Better watch news instead of looking a "nice" screensaver but without any practical utility
