How to control this kind of neopixel screen?

The facade of the INTERCONTINENTAL hotel in MIAMI is illuminated with LEDs representing video animations of the most beautiful effect.
Each hotel window is fitted with a strip of LEDs.
An exemple : https://www.youtube.com/embed/L0GlTYYHrUk

I would like to reproduce this kind of screen in reduced size simply with addressable neopixel leds.

Do you have an idea of ​​the most optimized way to generate this kind of animation? Which file to use to control the LEDs? I would like to avoid reinventing too many things :slight_smile:

Do you also have an idea of ​​how to generate the animation file? From a video, from a computer image?

Thank you in advance for your ideas and advice :slight_smile:
