Need a realistic flowing-water effect for an addressable LED sheet installation using ESP32/WLED/FastLED

We need to create realistic flowing-water effect for an addressable LED sheet (SK6812) installation using ESP32/WLED/FastLED. I have no idea how to make this happen, i know a lot about LEDS, but not about programming pixels and the hardware needed to run it, i need some help…

Does anyone know where i can go to get this help from?

Thanks in advance, Scot
