VisiTimer

VisiTimer is a fun, new, freeware countdown timer app for Windows that you can use to time anything from baking a cake, taking a break, or rationing out time for kids to do things like play video games or use the computer.
The coolest feature of this timer is that you get a visual representation of how much time is left as it counts down in the form an image or shape being "filled-in" or "painted" progressively in a radial sweep pattern in synch with the set time as it counts down.

This makes it great for teachers or parents of young children who can't yet comprehend the concept of numbers counting down as time passes, as well as for those who just want a quick visual indication of the time passage without having to waste valuable mental resources processing numbers.
