I'm sure that a bunch of us out there (including me) have those "rotating number" clocks that look like little TV sets and have a little light inside.
I have seen two styles of those, and older looking saqure one (what I have) and a newer one with a more late 50s/early 60s curved design, and a bigger screen to fit in with the new technology
They must have made a ton of those, I always see them on eBay and in Antique stores, though they don't always still work.
