Earth Hour 2008
Well, it was a great success and Sydney ended up saving about 25 tonnes of CO2 emissions. This year, it's become a global event. At 8pm on the 29 March 2008, hopefully millions of people in different cities around the world are going to turn their lights off. On Friday morning we helped launch a small part of Earth Hour 2008: [www.earthhour.org](http://www.earthhour.org) [![earth hour banner](/assets/uploads/2009/earth-hour-2008.jpg)](http://www.earthhour.org "earth hour banner") Working with Leo Burnett, we created the site in Rails, with [Radiant](http://radiantcms.org/) for content management. There is quite a lot of flash video, so we used Lighttpd for better performance for streaming FLV video, with the rest of the site on several Mongrel webservers.
