We all know of the famous pics1.png flower, but could you make your own? For instance sparkling water or lava, grass blowing in the wind? It would definitely look awesome!
You can put in animated tiles with addtiledef2, but it’s really laggy sometimes.
That’s awesome! Thanks.
You can always make a tile animation script like I did 
edit:posted my tile animation script in the code gallery, feel free to use it as a reference to construct your own system or you can just use it straight out
