Last week I decided I didn't want to drive through Tulsa (I-44 is a pain through there), so I took the Creek Turnpike, which bypasses the city. I pulled up to the automatic coin basket at the toll plaza and was surprised to find what looked like a vane display. It was supposed to be showing the amount due for the toll, but was blank. I threw a few different combos of coins into it trying to get it to say something, but it didn't appear to work at all. I did see one at another booth that had one segment "on", showing the segments to be a flourescent yellow-green color.
I think my high school gymnasium's old scoreboards used to have sports-type displays. Not for sure though.
So have you ever ran across one of the standard game show displays that we're used to seeing on TPIR or other game shows in a non-game show context?
