A chat application that allows users to chat locally based on their device's geolocation.  Users can specify the radius within which they would like to chat.  This app requires that users allow their browser to share location information.  Works best with Chrome browser.

• Using media queries to make a screen responsive website

• How to sanitize user input to prevent XSS attacks

• Using HTML5's geolocation to calculate distance between devices
