Google has introduced a few new software "toys" recently
1) FOXNews.com - Where Are Your Friends and Family? Check Google Maps - Science News | Science & Technology | Technology News
"Latitude" allows users to let themselves be tracked by other users so that an icon of them shows up on their friend's Google Maps view.
2) New Google Mars Reveals the Red Planet in 3-D
Google Earth recently announced a module called Virtual Mars that lets you visit Mars, even soar through canyons and mountain ranges. The offering is based on 3D data of the Martian surface that has been made available to the public.
3) New Google Ocean Takes Google Earth Beyond the "Dirt"
Space may be one "final frontier", but not the only one. Google Earth has also released a module called Ocean that lets users visit Earth's aquatic depths, even soar through canyons and mountain ranges. Yes, I meant to say it again. The offering is holed to raise awareness of the beauty and fragility of our oceans.
