Countdown Clock

I have a problem with mornings - I stumble out of bed and into the shower when my alarm goes off, and end up standing under the water in a stupor for ages. By the time I come out, I'm invariably late.

What I need is a countdown clock, which lets me set not one but two alarms. The first one gets me up; the second one I set to the time I need to leave the house in order to be on time for work.

Between the first and second times, the clock 'counts down' with an annoying audio countdown similar to that used on the popular 'Countdown' show [link]. So wherever I am in the house, whether making breakfast, shaving, or pulling on my trousers, I can always tell how much time I have left.
