Translation Party
Translation Party brilliantly combines the 2 uses of machine translations: generating funny translations and to test the quality of a translation. An English phrase is entered and Google Translate will continue to translate between English and Japanese until an "equilibrium" is found. In other words it will continue on (sometimes it will stop if it believes an equilibrium will never be found) until the machine generated result is the same in both languages. It is only available with English and Japanese, but it's great fun and very addictive!
