One more thing that comes to mind: if you use Atlantis' graphics as a reference in order to understand how the code works (which is completely fine as long as you're not using the graphics), you may notice that the rain effect on the windows is sometimes below, sometimes above the window graphics. This is due to insufficient layer control in Graal. I wanted to move that rain animation into a gani, along with the windows, but never got around to it. So, if you want to go with a similar approach and use my code for it, you can/should do that.
