I like this as well. But audio alerts wouldn't work, as even a couple of people I party with on and off are deaf.

I think something pulsing would get old very quickly, on the eyes; and for those who sit close to their screen, could easily cause headaches and other discomforts.

Trying not to be a stooge but just info on the above. What if they put in a "white out" effect on the ability that procced? It turns also completely white while still maintaining that little ring around it that exists now?
