Great Tool!
Very organized and pleasant to look at.
Some things that you could do to improve:
Add more background pictures like a car or keys for someones 16th birthday, a house for a moving date, and beer/wine bottles for someones 21st birthday. You could also include pictures like Big Ben, Statue of Liberty, and the Egyptian Pyramids for specific vacations.
Another countdown form could be a thermometer-like tube representing the time between when you created the countdown and when the countdown finishes. The tube fills up closer and closer to the top. Or the same kind of thing but with an hourglass.
