That is a banging idea!
There is a demo at Adafruit to do a stop motion movie display where each frame gets displayed for a minute or so and the display slowly cycles through all the frames in a movie.
Would make an awesome diorama with the poles with speakers, some old cars, and the bermed parking places. Might need a smaller display to scale where it could all fit but would be very cool and the picture changing keeps it freash.
Actually, the drive-in theaters were known long before they were even invented. It has been thoroughly documented that such drive-in theaters were very common even during stone age (see proof below):
Thereâs also an alternative to the drive-in, called drive through⌠adequately exemplified below:
I am good at spending my own money. I am VERY good at spending other peopleâs moneyâŚ
I was also very careful to say drive in and not drive through movie theaters 
Since Iâve been such a bad influence already I probably shouldnât mention the cheap rectangular flexible WS282 individually addressable RGB LED displays you could also control with ESP32âs using the WLED firmware (that you could also control with Home Assistant) that could maybe make something like the Goodyear Blimp flying over the city displaying messages. <Thatâll give you a few more things to GoogleâŚ>
And about all the streetlights in townâŚ
I do some coding which I believe is Java at school but not sure how much that would help.
I have been putting off buying a few of those screens to play with as I didnât think the resolution would be any good, those look great.
Are they the 1.28" 240x240 displays?
The displays are generally rectangular not square so the horiz and vert resolution wonât be the same. Some of these will be touch screens with non touch being a little cheaper, for my projects I havenât done much with touch but it can be there and you can just ignore it.
I mean like these.
Yours have the surface mount connectors rather than the ribbon cable connector in the one I linked.
Oh right, I forgot I had shown the round one. The Waveshare isnât a bad choice when youâre getting started and arenât ready to dip into the Chinese websites, but youâll spend a lot more for them. I bought them on Aliexpress on a link similar (but not) this: https://www.aliexpress.us/item/3256804295713253.html and soldering pins on them isnât an issue for me, but they were so cheap I ordered a few of them just to play with. It was frustrating to figure them out at first and while Iâm a programmer I tend not to have the visual skills to decide fonts, layout, colors to make things pretty.
And what I got has through hole pins which do require soldering, but thatâs still a LOT bigger than âsurface mountâ.
Once you get a little bit comfortable shopping aliexpress, shopping for small displays, processors, sensors can get very addictive. One thing to watch for is the shipping charges, they can add up fast and different vendors calc it differently. While youâre there there are temp/humidity/baro sensors, light level, VOC, laser particle sensors and things get tempting fast. I love Amazon and itâs great but youâre going to get a retail experience and pay for it.
