Hi, guys. Does anyone know if such a thing as interactive/living wallpapers exist? It would be really cool to have for example a wallpaper showing some medieval fantasy city with moving crowds and perhaps even sudden unexpected events like a dragon attacking the city or so on. It would be a huge bonus if you could affect the events of the wallpaper with your mouse.

I know I'm asking a lot so any kind of information would be hugely appreciated. I'm not good at googling so I wasn't able to find anything of the sort with a quick search.

Thanks.
