This
website will put a big digital clock on your computer screen, but the advantage is
you tell it how many minutes you want in an hour! So if you tell it there are 66 minutes in an hour, it will run just slightly slow -- almost imperceptible...and you get a free 6 minutes for lunch (or whatever). I am thinking of using it in meetings and do the opposite - tell it there are 50 minutes in the hour, when the clock reaches 12:00 the meeting is over! If anyone thinks of even better ways to use it, let me know!
