From Butternut Software:
Fun, unique, countdown timer that visually displays how much time has passed using any of several cool, built-in graphical images that are filled-in progressively in a radial sweep pattern in sync with the time as it counts down. This is great for teachers or parents of small children who can't yet comprehend the concept of digits counting down or those who might want a quick, visual indication of how much time is left without wasting valuable mental resources processing numbers. You can also use your own image or a simple, custom-colored or gradient circle. Many sounds to choose from as an alarm or use any WAV file on your computer. You can save preset times for quick and easy re-entry in the future should you need to set the timer for the same amount of time often. Also, several instances of the timer can be ran at once, and labeled to indicate what each one is being used to time.
