Students of the ZHAW Winterthur (Switzerland) built a live-flight tracker as their graduation-project. It shows the live airtraffic over Zurich, Switzerland on a Google-Map...
The original app can be found here: http://radar.zhaw.ch/
This application is now available in Secondlife, built in 3D! The airplanes are rezed according to their map-position and altitude.
Where available, the carrier-logo is shown on their tail.
