Vicinity is a simple application that returns the latest tweets of other Twitter users in your current area. You can choose to view those in the default radius (10 miles) or specify your own by appending "?radius=your-radius-here" to the end of the URL.
Version 1 of Vicinity is the first in a series of simple web apps showing off some neat things that can be done in a browser. In this case, we are using the HTML5 geolocation spec to obtain the location in the browser client-side (I've also enabled Google Gears for those of you who are using a browser or device that doesn't support this particular HTML5 spec yet). All calls to Twitter are done in Javascript, which means this entire little application is running solely on the device you are using.
Soon, the new Ravsonic.com will debut, which will have a list of all of applications. Also, Snic.us will contain all the little proof-of-concept apps like this. Finally, follow me (Lee Adkins) on Twitter or on my personal blog ThisIsLee.com
Thanks for checking out Vicinity!
