So, I see an example of an animated NPC (creepy surgeon) and think that It could works for water
My idea is create an animated NPC Fountain where players can trow coins, or fill empty bottles (maybe for a quest, I dunno).
Of that way, we could animate water and give fountain a use on game without start a map nightmare.
Animation at 3 frames faster:

Also I change a little the fences on "TestTown" map based on fountain texture
(thinking about add that fountain on Test Town, or where can be useful).
It´s still an unfinished idea, but I will try to put it on to can test it on local.
When I get more content sure I share the update .zip for the curious one.
