As much as I originally liked the green circuit board background, after a few months I think it's time for a change. Well, more like some variety. I have updated the site so that the background and highlighted colour is dynamically selected by a pool of images I have set. This is done via php, overriding the stylesheets.
Images are from places I have visited. Don't worry the circuit board is still there too. I'm sure you would miss it :) There is also a new section on the sidebar that tells you a little about the background. I hope you like it.
