Organisers handed out around 70 of the One Laptop Per Child XO notebooks to linux.conf.au attendees -- here some of the delegates test out the tiny XO's networking capabilities.

OLPC's XO laptop has a built-in camera that allows users to video conference.

The XO laptop comes with a sonar application, which uses the computer's built-in microphone and speaker to build a sound-based map of the surrounding area.

Conference delegates were treated to a giant screen displaying a Windows error, on its side. Pictured here with the "blue screen of death" is CNET Networks Australia's video guru Matt Oxley.

The blue screen displayed the standard message that Windows users know and dread: "A problem has been detected and Windows has been shut down to prevent damage to your computer."
