There used to be a widget you could get from the likes of ThinkGeek that would spam the "off" IR signal for lots of tvs and commercial displays. I remember seeing it as a neat trick twenty years ago, but more and more.I wish I really had one. Lots of storefronts have absurdly bright screens on all night now, project moving shit onto the sidewalk and just generally bombard your vision with distraction.

I imagine you can use something like a Flipper to get a similar "put-outer" device nowadays but I haven't come across anyone using it in that way.
