Don't worry - people get really used to flashing and screaming. I didn't pay much attention to TV / screens around me a couple of years ago. For about 5 years now, I live without a TV in my home - and I can see the effect. In pubs, I have to sit with my back to the screens, otherwise I can't stop looking every couple of seconds... it flashes, there's stuff happening, I can't have a normal conversation if I see it. Even typical slots machines are way more distracting than they appear...
