Changes to layout

Having neglected this blog for a while, I have made a few changes. As well as a new layout, there is a list of interesting items from other blogs plus a feed from Last.fm of music I have recently listened to. I will try to put some more videos on from YouTube although I am not sure what happened to the formatting of the previous one (it should be in the middle of the post, not off to one side). I have added a feed so that you can add new posts to a RSS reader. It works with Google Reader if not others.
