This is a timer application that uses color instead of numbers. You can setup any number of color transitions with any color. Great for presenters where keeping track of time is distracting (and the colors can easily be seen from across the room). For example,
1. Display green for 10 minutes
2. Display yellow for 2 minutes
3. Display red
Also good for children who cant tell time yet, "Timeout is over when the light is green..."
