One of the Google Geo API team developers, named Roman Nurik, took one of the really cool Google Earth plugin demo applications (the Milktruck game) and created a really useful application. He combined Google’s map driving directions with the Earth API plugin to create a 3D driving directions tool which also lets you simulate driving along the roads with a 3D car. You should check out his 3D Driving Directions here (requires the GE plugin for your browser – IE, Firefox, or other Mozilla browsers supported). You can also read his post at the Google Geo Developer Blog where he explains how he developed the application. Well worth a read if you’re an aspiring Geo developer. Amazing!

Yes, I checked it. The application is one of the best creations and it will help the beginners very well!!!
