ICAO/NATO Spelling Alphabet Trainer RasPi

Press a green flag to start. Answer a question by typing the complete costume name and press Enter. If you answer incorrectly, an error counter appears. At the end of the quiz the time it took in seconds is shown. You can move the sprite on the stage by pressing the arrow keys, but first you must click outside the answer field. You can also drag and drop the sprite. This program trains you in the ICAO/NATO spelling alphabet. The spelling alphabet is taken from http://sv.wikipedia.org/wiki/Bokstavering and http://en.wikipedia.org/wiki/NATO_phonetic_alphabet .
