I was thinking the same. My £20 DVD player has a greeny-blue fluorescent display, complete with a round "eye" to show if the machine's running in reverse or forward modes and at what speed. It looks very like an old magic eye.
But I suspect the cost would be astronomical unless they were being produced in tens of thousands
What about a backlit moving-coil display? RS used to do some tiny, round m/c battery-status indicators, which were designed to "wink" a bit like a magic eye according to the battery's voltage. Here's something similar:
