I used to live across the street from AT&T Plaza in downtown Dallas, which now has this 70-foot jumbotron monstrosity lighting up 10 city blocks, 99% of the time with a screensaver: https://attd.imgix.net/wp-content/uploads/2020/10/13155803/A...

So glad I moved right before they started construction on this. This is on 24/7, and how that is remotely acceptable in a place people live I have no idea.
