There are plenty of twits around town, but if you want to Twitter around town, perhaps you may be interested in the new augmented reality Twitter app - Twittaround.

Using the iphone's camera, live Tweets pop up on the screen, enabling you to see where the tweets are coming from and how far the person is away from your location. It uses the compass plus GPS technology, which restricts the app to the iphone 3GS only.

OK, so unless you're a Twitter obsessive, the app isn't so great at the moment, but there are plans in place to introduce live augmented images of important buildings and businesses. Soon the days of walking around town with a giant fold-out map will be gone. With this app you should never have to ask a stranger for directions again.
