I'm looking for a script that I can update manually to show my website's progress. Something like in the shape of a thermometer, but the red area will grow as I increase my figures. I need to be able to specify a number at each end as I might be going from 0-50, 50-100, 100-500 etc... and need to be able to start the 'counter' again at each of these intervals.

Can anybody help me with this please? I seem to remember something like this on milliondollarhomepage tracking how much money he'd made.
