The live count is also kept in the page's title, visible in your browser tabs.

I think it's cool because of how QUICKLY you can add a timer and then "setitandforgetit", it's visible in your taskbar too for handy glances downward while you're killing time for a specific # of minutes (e.g. me at work end of day,about to catch a bus/train at a certain time)
