I have found several timer gadgets that work just fine, but it would be handy to have one that would automatically reset to the initially specified interval each time the countdown ended.
(say I want to set the timer for 5 minutes, and when it ends, click once to start another 5-min count, over and over, without having to re-enter "x" minutes every time I use it)
I am not particular about colors (especially when asking for something for free

), but basic black or steel gray with green fonts would be a nice bonus.

Update: Nevermind - I found something that will suffice under "Alarm Clock" in the Windows' gallery
