Surely You Are Joking, Google Translation

Google launched a translation bot for the Google Talk service. Basically you can just add a translation bot to your chat contact (e.g. en2fr@bot.talk.google.com would provide English -> French translation), and talk to him as with any other friend, and it will provide an instantaneous translation!
