With Morse Droid, you can translate a full text into a morse code to which the phone will then vibrate. You can choose to ignore or translate non alphanumerical characters, and to repeat the Morse vibrations or not.
More features are to be coming, like Morse to text translation!
Suggestions are welcome!

NEW in v2.1: You can now translate morse into text + the interface has been entirely redesigned!
