BreakTime

nolen.royalty

BreakTime allows you to run Brick Breaker (aka Breakout) from inside your Google Calendar. The ball will bounce around your screen and shatter your meetings. Prevent the ball from hitting the bottom of the screen by moving the paddle around with the arrow keys! At the end of a play session you'll be asked whether you would like to actually decline all of the meetings that you shattered. If you check yes BreakTime will actually decline your meetings!
