Here is a nifty little Twitter implementation from the nice people at OneHourTranslation.  I hope all you Twitter geeks are happy now, that your voice can be heard in so many languages.

Here are the instructions:

• Send @twitrans tweets like: en2sp I can now tweet you in Spanish! When are you coming for a visit in New York?
• Wait a few minutes. While you wait we route your text to our translators at OneHourTranslation.com
• Get the translation back in your Twitter home page: twitrans @twitter ¡Ya puedo decirte pío pío en español!¿Cuándo vendrás de visita a Nueva York?
• To get more help, please send @twitrans help or @twitrans codes.
• Available language codes: Arabic-ar, Chinese-zh, Dutch-nl, English-en, French-fr, German-de, Greek-el, Hebrew-he, Hindi-hi, Italian-it, Japanese-jp, Portuguese-pt, Russian-ru, Spanish-es

Have a go at it here @twitrans

P.S. You need a Twitter account for this.
