Google Maps has become a massive success and people continue to find ingenious new ways to amuse themselves with it. One example, isoma.net/games/goggles.html, is a flight simulator that uses images loaded from Google’s mapping service, allowing you to fly around your chosen location, and even strafe the landscape with gunfire.
There are many medical sites, but if you want British then perhaps only the recently relaunched www.nhsdirect.nhs.uk will do. New features include a “feeling low” algorithm in the self-help guide, which attends to every common health problem. There is also a local health service search engine.
