Toggl use a favicon animation to show when a timer is running or not, but it's as simple as red icon on, black icon off. More distractingly they also animated the title to show the timer, but thankfully there's now an option to disable that.

I find it pretty distracting having anything in my browser titles animated, just catches your eye now and then and breaks my train of thought.

A bit like the annoying ripple effect on buttons and hovers in Google's material, it's excess visual clutter that my brain, at least, decides it needs to pay attention to.
