The Computus Engine is a personal project; an ongoing exploration of how time is measured and how new technology might let us interact with it. As with all such efforts it has gone through periods of intense activity and periods of dormancy. But ever since I've had a presence on the web there's one ritual I've managed to keep throughout. Every month since January 2000 I have produced a new desktop wallpaper. Here's a short visual history of that project.

2000

The initial run of desktops were all graphic design experiments of vastly varying success!

2001

October 2001 saw the first calendar of events incorporated into the design.

2002

Photography was introduced in 2002.

2003

Two themed sets in 2003 and some experimentation with more calendar information.

2004

Two sets from various trips and a further experiment with layout.

2005

In 2005 the design settled down to the now familiar top bar.

2006

2007

2008

2009

2010

Since 2010 the calendars have lived here on computus.org.

2011

2012

2013

And finally a sneak peek at next year's set. As usual they feature some of my favourite photos from the previous year and in fact most of these were shot locally on Worthing seafront. Have a great 2013!
