Despite all the heat Google has taken for Street View in many countries for things like invading privacy and stealing WiFi data, the service is cool. My town has very limited coverage when it comes to Street View, but the coverage it has comes in very handy when I want to see what a place really looks like if I am not sure where it is.
There are many other cities around the country that are lacking coverage altogether. Despite some holes in the US, Google has announced that Street View is now available for Antarctica. The catch is that the coldest continent has no actual streets so its more like Google Walk View. The new coverage along with coverage for Brazil and Ireland means that Street View is now available for all seven continents.
The images that Google has for Antarctica are of Half Moon Island and you can see landscapes along with penguins in the Antarctic cold. There are also images used in the service that were posted by users that can be viewed.
