wordBuzzer

The app is to write a small multiplayer language game for one device. The game screen will contain a "buzzer" button in each corner of the screen - one for each possible player.
The players will see a word in language "one" in the middle of the screen. While this word is displayed, a word in language "two" will fade in from some border of the screen, move over the screen and then fade out again within just a few of seconds (1-3s). After one word is faded out, a new word is faded in.
The players hit their buzzer when they think the correct translation set is presented. The first one hitting his button will either be right or wrong and the next round is started with a new target word in the middle. There should be some feedback to the players telling them how well they are doing.
It should be ensured that the correct word will be shown at a frequent enough pace.
