GlobalView is a twitter client - but one that gives a different view of Twitter - a Geographical One.
Select the global time line, a trend, or any search you can put together. GlobalView will collect tweets, work out where they come from, and plot them on a map.
You can look at individual tweets, or have GlobalView show a constantly updating tour of tweets.
Possibly youll come across someone interesting to follow on a permanent basis - if so, just hit the follow button!
Found something illuminating - retweet it!
Great as a stand alone client - and great as alongside a traditional twitter client.
Had a profound thought while watching the world go by - tweet it!
