There’s a mall-like plaza within LAX. Seems new-ish, I dunno. But there’s a vertical screen with ads, about 3 stories tall. Then on the hour, it becomes a living clock. Well, the screen projects an intricate Busby Berkeley-style musical of several art-deco women dancing inside the workings of a clock. It lasts a couple minutes and is quite impressive. That’s what it did at 8am last Wednesday, anyway. Every hour could be different for all I know.
