 ===== PolyGlot Chat Application =====
-AmbiScrabble is a digital version of a scrabble-like game where players work collaboratively with their iPhones to form words. The screen shot below shows the AmbiScrabble application on the iPhone.
+PolyGlot chat is a distributed chat application that enables users to write text messages in their preferred language and have the text message automatically translated to the receiver's language.
 ==== How the chat works ====
+The application works as follows: When a chat application is started the user is prompted to specify the preferred language.  Then a text chat conversation can begin with a selected a buddy. When a chat message is received from a buddy,  it is automatically translated from the buddy's language to the user's specified language. For instance, if Bob (an English speaker), sends a message "Hello there" to Tim (a Dutch speaker), the message is displayed as "Hallo daar" on Tim's chat window.

+==== Application design and implementation ====
-The game works as follows: Players are organised in teams and each player has a rack of letters. Letters are consumed by forming valid English words. The team that first consumes all its letters wins. Players belonging to the same team can exchange
+The PolyGlot chat application has been designed in a peer-to-peer fashion without assuming a centralised server. We implement the chat logic and distribution concerns of the application in [[iScheme|iScheme]], while the graphical user interface (GUI) is implemented in Objective-C using the Cocoa framework. The translation happens using the Google translator API which is accessible from iScheme, thanks to the Objective-C and Scheme symbiosis.
